Rigs-of-rods: T813 Material/texture issues

[CuriousMike56]

• Spawn Tatra T813 Dakar
• Then spawn this after: Tatra_T813_Kolos.zip
  
  It's mainly the pink texture that's the issue.

This started to happen when you modified the T813 Dakar. Could you paste your changes?

I converted most of the materials from t813.material to managedmaterials:

The bright pink is a managedmaterial-placeholder. It means the managedmaterial was defined, but for some reason it could not be set up on the target mesh. Look for anything unusual in RoR.log

[only-a-ptr]

It doesn't happen with the stock mods linked above. I'll try to re-apply @CuriousMike56 's changes
UPDATE: Uhh!

RoR.log doesn't help. I'll add some diagnostic output.

[only-a-ptr]

I found the issue: we're not using STRICT resource management. Specifically, we do Ogre::ResourceGroupManager::createResourceGroup(inGlobalPool=true). As a result, resource groups won't protect us against mesh/material name collisions between mods.

In this case, Dakar generates the managedmaterial placeholders (in RG1) and the Koloss picks them up, even if created in RG2. Upstream doesn't handle this, so I added it: https://github.com/only-a-ptr/rigs-of-rods/commit/1ad65317df4fefdcded523c1e2d43f2633fcfade - but without STRICT mode, it won't have any effect. In fact, right now OGRE doesn't even load Koloss's meshes in this case, it will pick up those from Dakar (same names).

is this related maybe? https://github.com/OGRECave/ogre/commit/5407613c6efa6167d164f42b4418923d3e701995
