Texel Density Masterclass - For Rendering & Real-time Graphics (Games)

Texel density is essential for maintaining the right texture sizes in real-time graphics applications such as games. It helps prevent over-detailing, under-detailing, and wasted detail due to downsampling. Additionally, it prevents unnecessary VRAM wastage by ensuring that textures are appropriately sized for the objects in the game world.
In a static rendering context, it also helps to improve render speeds and reduces the amount of RAM required for textures in large and complicated scenes.

Very informative and useful tutorial. I look forward to the release of the next Masterclass. Thank you!

[@rogaalik1379]

Awesome Video

[@nurb2kea]

Thank you very much. That was a good one and corrected a couple of mistakes I do/did ...🙂🙃

[@Leevy27]

Very informative! Thank you. I'm eager to see how to do texel density with UV Packmaster or perhaps ZEN UV.

We'll cover a bunch of that in the UV/texturing masterclass videos and the game asset pipeline series we have planned :) - Tristan

[@CinnnAmonnBun]

This cleared up so many of my doubts.🙏 Thank you.
17:41 How does this work ? Would love to see more videos like this.👍

[@HugeMenace]

Glad it was helpful! And definitely, we'll cover all those packing options in more detail in the UVs masterclass I'll be working on next. - Tristan
