I'm venturing into foam scenery for the first time and am finding these two videos on foam rocks to be invaluable. I also really appreciate your sense of humor and wit that's interspersed throughout! Thanks again for creating these!
I don't do the model railroad thing but these procedures will help me with the rock work in my lizard's cage. You have a good presence in the videos - reminded me of Bob Ross - and that is a good thing! Thank you.
This was posted on my birthday last year... How did I not know about this.. This is a gift! I needed to know how to make it more realistic! I thank you sir!
Nice job!. what I have been trying to do that you do with a brush is i use a hobby knife to carve some random strata and then push a nice pointy stone with plenty of texture into the foam on the crack edges to make them pressed in, which also gives the fractures (it also leaves an imprint of the rock texture which is a nice add)
I am building a 1:10 scale RC track and this application is absolutely AMAZING for any application. Great video! If you want to make a great rock scene for your models, WATCH THIS VIDEO....even if you are a geologist.
To get a longer working time out of your plaster, mix it with very cold water. I also put a teaspoon of baking powder in each cup of plaster and this also seems to extend the working time of the plaster. I can get a working time of about 20 minutes from this mixture. I have seen videos from Boomer Dioramas and he uses Fast Mache to fill the cracks and to form overhangs and earth. The Boomer Diorama is a fantastic site...This is Bob Ross on steriods...
Great job and nice technique. Can the foam pieces be glued together with white glue? Also what are all your foam pieces glue to? Thick Cardboard? Thanks in advance. Phil
Bob, I have no idea where I got that knife. I've had it for decades. the only markings on it are: MOLYBDENUM VANDIUM STEEL JAPAN I seem to remember that it was a very cheap knife, so You might start looking in dollar stores, or the like.
Yep, 2" foam. Keep in mind that this is in O scale so similar results could be had in HO with 1" foam and so on. The only reason I pieced the foam together like that was that the basic landforms underneath are beadboard and I was going to use plaster castings initially.
I've roughed out the basic landforms out of stacked poly styrene bead board, only because I was going to use plaster rocks cast in latex moulds over the top. The extruded poly styrene blocks, that I carved the rocks out of, could really be attached to almost anything. One could build the entire hillside out of the extruded foam, it would be more costly, but would work just fine. I've done that myself for smaller hills.
thank you. You know its funny, i have the same material (the extruded foamboard) but whenever I cut into it, mimicing what you did, the layer undernearth (regardless of the depth of my cut or the blade I use) reveals a "crumby" surface as opposed to the cracky creggy texture, that we're trying to achieve here. Any thoughts on that? Thanks.
The foam was 2" thick on this area. The paint was thinned with methyl hydrate or methanol. straight water would work as well, but the methyl flows better.
You could, but drywall mud shrinks a great deal and takes much longer to dry. It might take two coats of mud and a day or two to dry as apposed to 30 mins for the plaster but should work.
No video of that, sorry. The pieces were just cut out of a larger sheet with the same knife I used to carve it. They were attached using spray foam insulation (the kind you use to fill gaps around windows and such).
Any Height you want, if you make yours the same size as mine, approx. 2 ft. high, they will represent cliffs that are 4 times as tall as mine. In O scale my cliffs are about 50 ft. tall, in N scale they would measure out at about 200 ft. It all depends on what you want to represent in model form.

Clearly explained and easy to follow - and looks great, too! Thanks so much for sharing.
You, sir, are the Bob Ross of modelling! Excellent work! A heartfelt thank you!
Among many videos on this topic , this is one to watch.
I think a Happy Little Fissure lives right here.....
This is an extremely helpful tutorial. You have a very nice teaching style.

Glad they could be of help, Mark.
Hope you consider posting more of your layout
@@rupheandtumbelle was Bob Ross your brother ?

"It took the planet a few billion years to figure this out, so, what hope do I have in a lifetime?" Ahahaha. Informative and entertaining.

Bravo, même si j'ai du mal à comprendre l'anglais, la vidéo est très claire, bien expliquée par le geste, félicitations !
As a model terrain aficionado, I can only approve. Excellent work!
Thanks Evan.

Really helped me make a cliff side for a background of my Terrain piece! :D
As an alternative to the stubby brush for adding texture to flat surfaces, try a file cleaner. Many steel teeth on a brush background, works great.
Thanks, I've found a small wire brush that works well also.
You could also use a ball of foil to give the rock texture

Great tutorial, I will use your technique for the finish to my Harryhousen cyclops diorama thank you
Looks great 👍
The Bob Ross of foam carving
Let's put some happy little rocks... Right "dere"
The intro was brilliant.
Great job and nice technique.

Why is this so satisfying to watch..?
Great Tutorial!!
Bob, I have no idea where I got that knife. I've had it for decades.
the only markings on it are:
MOLYBDENUM
VANDIUM
STEEL
JAPAN
I seem to remember that it was a very cheap knife, so You might start looking in dollar stores, or the like.
+rupheandtumbelle I was going to ask. That knife looks perfect.
thanks so much.
this rocks!
is that styrofoam I am not from England, or some special foam, is the same foam you put tv inside when you buy new tv?
It's the type of foam you'd use to insulate your house. Extruded polystyrene.
Thanks for the video
Impressed.
Thanks CAM and JOE DH I had fun making them, The videos that is, although carving the rocks was fun too.
Would this work for a warhammer project
No idea what a warhammer project is!
Heck yeah it would work for that. I build gunpla and make diorama for them, and this type of thing makes some great scenery.
Have you tried to model dragon rocks?
Very good video
Great Job, Is that 2 inch foam u are using?
Yep, 2" foam. Keep in mind that this is in O scale so similar results could be had in HO with 1" foam and so on. The only reason I pieced the foam together like that was that the basic landforms underneath are beadboard and I was going to use plaster castings initially.
+rupheandtumbelle
I'll buy a 4ft piece from U. No lie. I'll pay whatever it is worth. Live in Pa
It's just standard XPF eXtruded Polystyrene Foam. Available at any hardware store, used for insulating your house.
Hi, great video, can I use this technique to make an 3D aquarium background?
Would probably work, but keeping the foam down under water could be a pain!
Warhammer is a tabletop battle game
It would probably work fine. give it a go.
Hello very nice. Question, what are the foam blocks glued to?
I've roughed out the basic landforms out of stacked poly styrene bead board, only because I was going to use plaster rocks cast in latex moulds over the top. The extruded poly styrene blocks, that I carved the rocks out of, could really be attached to almost anything. One could build the entire hillside out of the extruded foam, it would be more costly, but would work just fine. I've done that myself for smaller hills.

how thick is the foam board. one inch or two inch. Also what was the fluid you mixed with the paint in the bottles
The foam was 2" thick on this area. The paint was thinned with methyl hydrate or methanol. straight water would work as well, but the methyl flows better.
do you think your could use dry wall mud in replace of the plaster of paris?
You could, but drywall mud shrinks a great deal and takes much longer to dry. It might take two coats of mud and a day or two to dry as apposed to 30 mins for the plaster but should work.
Do you have a video on how you cut the foam pieces and mounted them? Thanks
No video of that, sorry. The pieces were just cut out of a larger sheet with the same knife I used to carve it. They were attached using spray foam insulation (the kind you use to fill gaps around windows and such).
@@rupheandtumbelle I'm going to give it a try. You did a great job. Hope mines comes out as good as yours.
@@MrURA1986 Good luck!
Where do you buy tho foam? What do you glue it down with? I understand the foam spray for the holes
Any building DIY store should have it. Extruded polystyrene is used for insulating buildings. I use the spray foam to glue it down as well.
hi very nice job what would be a good hight for N scale
Any Height you want, if you make yours the same size as mine, approx. 2 ft. high, they will represent cliffs that are 4 times as tall as mine. In O scale my cliffs are about 50 ft. tall, in N scale they would measure out at about 200 ft. It all depends on what you want to represent in model form.
Bonjour en regardant votre vidéo je ne me rend pas compte de la grandeur de vos panneaux pouvez vous m'aider merci.
Where do you get those big pieces of polystyrene?
Any home DIY store will have what you need. It's Extruded Polystyrene foam for use in insulating your house. I just cut up a 2" thick piece of it.
Do you like Bob Ross ? :)
