This is the very best video on how to create alphas for zbrush I've ever seen. Thank you for your hard work. I have subscribed.
you are very welcome! Thank you!
Inkscape- a filter -blur -feather or straight up fill stroke -blur slider[above opacity slider.
Thank You.. I have forgotten that how alphas were made.. Thanks to you, remembered

Not a problem! Glad to help!
Nice lesson, thx man!
Absolutely :D
You can use Substance Sampler to extract height information from an image so it isn't quite as noisy too!
tnx my lord
Thank u so much!!!!
Thank you so much for the video, Amazing

Thaaaaaaaaaaaaaaaaaaaaank you
You are so welcome!
The issue I'm having is , the alpha image looks like it's under layers of my already textured model. So, the alpha image doesn't appear to look like it's on top of my model. I also wanted the alpha image to look like it was carved downward into my model. Please help
Can I open a alpha brush with my photosop and use it?
You can't use a ZBrush Brush in Photoshop, but you can export out the alpha to use in Photoshop. Just click on the alpha icon on your brush, and click export which is located at the bottom.
Hope that helps 😄
how do i make 4k resolution out of my alpha? kindly help
If you want to have a 4K map, set the pixels to be 4000 x 4000 (or higher) with a dpi of 150-300 and then follow the same process from there. It’ll be a much larger file, but should give you what you are looking for.
Quick tip: If you see that the images you are working on at that size seems pixelated or stretched at all, then you’ll need to have high resolution files that match that scene when working at that scale.
Hope that helps
It's amazing how many skilled artists STILL don't understand that 'resolution' in Photoshop is nothing more than an instruction for a printer, as in how many Pixels (Previously called Dots) are to be forced into a single inch of physical space. It has nothing to do with AntiA on an image which remains on a computer. 72 is standard for images which are to only be digital, therefore it's not "low". This literally could be 1, and it would make NO difference when creating this type of image.
Don't believe me? Make two documents at 512 x 512, one with 72 PPI (used for digital) and one with 300PPI (used for small printing e.g. A5 leaflets) Copy an image from any other source and paste it in to both these documents. See there is absolutely no difference in pixelation or anti-a on screen. Hit Print on the 300PPI and then the 72PPI image, and see the difference in how it would print. It is literally telling you what it is 'Pixels PER inch' (of whatever you are printing on).
Hello.
Thank you so much for taking your time to write this comment out. Allow me to explain my train of thought. First I would like to say that you are not wrong. In fact, yes, DPI really matters most for image resolution for a physical print. However there are some reasons why you would want to choose a resolution of around 150 to use for an alpha.
To optimize your 'on screen' resolution, 72 DPI is 100 % perfect and nothing more is needed. However, when creating an alpha file to be use in Zbrush or any other 3d software, I have found that a large DPI helps in image stretching when you are using it for detail projection. It helps retain sharper lines and can result in a much cleaner file as you stretch the image over your mesh. At 72 DPI, it gives me the detail I want, but I find myself spending more time cleaning up the mesh after the alpha is placed. At 150, it gives me better resolution in which I can cover a larger portion of my mesh while retaining the most amount of detail possible with very little clean up. And since my work gets manufacture via 3D printing, injection mold and castings, I would much rather have a slightly higher resolution to have great results.
Could you leave it at 72 dpi at 512x512 and see very little change? Yes.
Will there be a night and day difference between 72 - 150 - 300dpi? Not really.
Like I explained in the video, it really just ensures a good file size and quality that allows the image to be its best; giving you the best results possible.
Again, thank you for taking the time to give me your feedback on the video.
It means a lot to hear back from everyone as I take note for future videos.
All the best.
Yeah, when my pizza guy asks me how many slices to cut my pizza, I always tell him 8, because I honestly can't eat 12 slices. He once sliced it into 6 slices, and I asked him for a refund, because, where are my other 2 slices!?
This is pretty much what you're saying here when you're talking about the DPI resolution, heh..@@IRSculpts
sorry ut its not the right way to create alphas for zbrush cuz in this way you alpha textures will be very sharp and u cant use them to detail your models
exactly, that guy is wrong because you need to create blurred value of black to properly use it in Zbrush
