Randomizer issues

(1/1)

LeSill:
Hello, folks.

I tested the functionality of the shader RANDOMIZER. First of all, I read somewhere that it works even when the material tag is set to CUBIC mapping. Well, that does not work for me. When I switched the mapping to UVW, it worked. It worked, but it could have performed better. I've set the randomizer to randomize depending on the MATERIAL NAME. Then I clicked RANDOMIZE EACH TILE and set the number of tiles to 3. Even with the BLENDING set to 0.25, I could still see the sharp edges of the tiled textures. So I turned off and on the blending and discovered that it just blends the tiles' borders, not the repeating texture within the tile. It would be ideal if the texture inside each tile could be blended as well, eliminating the stark noticeable edges.
Maybe I did something incorrectly. Could someone check that I understand it correctly?

Thanks

Your dirt texture is bad. If you want seamless result, you MUST use seamless texture. Randomizer is meant to disguise repetition, not to eliminate seams. For seams elimination you should use triplanar, but in any case your input texture must always be seamless, unless you want seams in your final render.

LeSill:
I intentionally picked this texture with substantial seams to test how the rondimzer works. Thank you for confirming that the seam issue is due to a non-seamless texture, which the randomizer cannot address.

The best I could come up with was using the "mirrored tiling" option in the Corona Bitmap and then using a mix of Mapping Randomizer and Triplanar. :)
