Summary	0005718: Vertex blended model material unable to support two bumpmaps.
Description	As Greebo added a new function into DR 2.14 for exported .LWO models to retain vertex colours (blend data for vertex blended models) - - https://bugs.thedarkmod.com/view.php?id=5717 I figured it would be a good idea if support for more than one bump map's could be added for vertex blended models to the core mod. As it is, the mapper can only choose one atm, so blended models will look odd if the mapper isn't careful.
Additional Information	Here is an example blend material I made for NHAT4, no matter what I tried only tecond bump-map was ever shown in-game - textures/blend/cave_gravel_blend { qer_editorimage textures/darkmod/stone/natural/grey_cracked_001_ed surftype15 description "stone & gravel blend texture" // Vertex colour stage { blend diffusemap map textures/darkmod/stone/natural/grey_cracked_001 VertexColor } { blend bumpmap map textures/darkmod/stone/natural/grey_cracked_001_local (this bump-map 'is not' recognised by the engine) VertexColor } // Inverse Vertex colour stage { blend diffusemap map textures/darkmod/nature/dirt/stones_sand01 InverseVertexColor scale 3,3 } { blend bumpmap map textures/darkmod/nature/dirt/stones_sand01_local (this bump-map 'IS' recognised by the engine) InverseVertexColor scale 3,3 } }

nbohr1more 21.08.2021 01:02 developer ~0014308	Ah, I just noticed: grey_cracked_001__local has two underscores... It should be: grey_cracked_001_local

Bikerdude 21.08.2021 09:49 reporter ~0014309	Corrected typo above, but this doesn't fix/effect the issue. The game will only recognise one bump-map per blended material.

Bikerdude 19.09.2023 15:35 reporter ~0016068	All we need to do is have the bumpmap at the beginning of each vertex stage in the material def and only assign the 'vertex' and 'inversevertex' lines to the diffuse/specular stages. And on a side note we can add specular maps to the vertex stages aswell. after.png (27,226 bytes) after.png (27,226 bytes) before.jpg (72,144 bytes) before.jpg (72,144 bytes) image.png (1,284,382 bytes)

Bikerdude 22.09.2023 10:46 reporter ~0016078	I have a attached a test map so the team can get users to test this on low end GPU's such as Intel Arc or ATi/Amd to make sure it looks and works ok. before.png (544,670 bytes) after-2.png (805,401 bytes) BlendTest.7z (5,110,030 bytes)
