Blendmap quantity in page otc file

[bobz]

Hello,

I have the following page otc file:

height.png
6
; worldSize, diffusespecular, normalheight, blendmap, blendmapmode, alpha
4, dirt_diffusespecular.dds, dirt_normalheight.dds
1, asphalt_diffusespecular.dds, asphalt_normalheight.dds, surface0.png, R, 0.9
6, rock_diffusespecular.dds, rock_normalheight.dds, surface1.png, R, 0.9
5, sand_diffusespecular.dds, sand_normalheight.dds, surface2.png, R, 0.9
4, grass_diffusespecular.dds, grass_normalheight.dds, surface3.png, R, 0.9
3, gravel_diffusespecular.dds, gravel_normalheight.dds, surface4.png, R, 0.9

Everything works but the last line with gravel. While surface4.png has some red channel drawing, nothing appear.

From what I understand from the doc (https://docs.rigsofrods.org/terrain-creation/terrn2-subsystem/#format-overview), RoR supports 6 layers and 5 blendmaps, so it should be OK.

I have noted this in RoR.log

As you can see, it doesn't try to load gravel textures.

Am i doing something wrong, or is it an expected limitation ?

Thanks for your support

Do you have shadows enabled? Unfortunately they occupy one texture layer, which results in the last layer to be missing on terrains with 6 layers. Most notable example of this is Auriga, its detail layer is missing with shadows:



Currently the only solutions are to disable shadows (not ideal) or lower your layer count to 5 if possible.

That's it. Disabling shadows makes the last layer appear. So I will only use 5 layers. Thanks for your answer.
