In CAD system, we used ‘PBRMaterial’ and enabled ‘forceCompilation’ option. That seemed to help while loading multiple meshes as ‘effects’ (shaders) may be reused internally. Now, we use a custom NodeMaterial created using NME that’s using PBR blocks internally. We create & assign it for each mesh…

Adding @bghgary and @Evgeni_Popov about the force compilation and NME.

I don’t think there’s a forceCompilation option (?) There’s a forceCompilation method that you can call to force compiling a material for a given mesh but it won’t make things faster by itself: the compilation will be done straight when calling the method instead of when the mesh needs to be rendere…

[image] Evgeni_Popov: Maybe it takes a little more time in the NME case because the json files need to be parsed? Thanks. I’ll check on them. Though we don’t use json import, we used ‘Generate Code’ option from NME. Either way, I guess it may take some time there. Also, engine._compiledEffe…

Would it be helpful to capture a profile with the browser to see where things are slow?

In this playground sample , I’ve created 2 NodeMaterial objects using same NME snippet & also two PBRMaterial objects. In _compiledEffects console log, I noticed 3 effects are being created. Two are for NodeMaterials and only one for PBRMaterial. Since code of Vertex & Fragment shaders in both Node…

Thanks for sharing the info @br-matt . That fix from @Deltakosh helped. Here’s the modified code sample Now I see just one effect being created. Further, now it’s possible to set different color to the cloned NodeMaterial. That’s what we wanted!!!
