Terra dynamic materials

[Nickak2003]

I want to add dynamic/ procedurally generated textures to terra rather than the static ones loaded from the json. Assuming I already can generate these textures, what is the best way to tell terra to use them?

Just create an HlmsTerraDatablock via HlmsTerra::createDatablock, modify it to your liking, then set it via Terra::setDatablock.
As for the heightmap, Terra::load accepts an Image2 which can be created at runtime.

I notice that by default through the json, terra sets properties on the hlms to load it's textures, I think. I see that with this code:

Code: Select all

            Ogre::HlmsDatablock *datablock = hlmsManager->getHlms( Ogre::HLMS_USER3 )->getDefaultDatablock();
            Ogre::HlmsMacroblock macroblock;
            macroblock.mPolygonMode = Ogre::PM_WIREFRAME;
            datablock->setMacroblock( macroblock );

mTerra->setDatablock(datablock);

, I can set a datablock. My question at the moment is how do I assign a given texturename/id into the data block that terra would use?

I guess it would need to be a terraHlmsDataBlock rather than datablock, still, my question remains.

Cast to HlmsTerraDatablock* and call HlmsTerraDatablock::setTexture( TerraTextureTypes, tex );

Is that what you're asking or did I misunderstand?

Cheers
