So that's a target of 256 pixels of texture across a distance of 1 meter in the game. Measure a branch with leaves on it. If the branch is about a meter long, then it should be 256 pixels long. Simple.
Your color divided by 256 = Color value between 0 and 1. For example : 127 (gray) = 127 / 256 = 0.496. Note that our color widget is in linear space (not sRGB as in Photoshop).
damn, those shader settings look daunting!! The bigger of the two matcaps you shared also crashed for me when zooming. I was able to fix it by clearing out the surface bump texture in S3 and also set the CanvasBump scale to 1 just for good measure...it didn't look like there was any noticeable difference in the visual…
Ok nevermind it only worked out that way when the boxes were the exact same size. Do boxes need to be in a power of 2 or power of 8? Like 256 x 256 and a certain width?
Use 16-bit images. 8-bit images can have only 256 different values per channel, and because heightmaps are in grayscale that leaves you with only 256 different possible height values.
I am having a weird issue with a small 256 x 256 graph. Pressing spacebar appears to shift the pixels slightly causing a break in the tiling on the output image. Node graph is pretty simple, this node is a safe transform at 45 degree rotate. Any ideas?
