Reading render-time mesh

[Anonymous]

I'm working on a render plugin for 3DS Max and I'm having problems reading the render-specific object meshes, e.g. MeshSmoothed mesh with a different number of smooth iterations (using Render Values).

I seem to be stuck with the mesh visible in the viewport.

I'm using this procedure to get the final mesh:

meshNode = <the object's INode>
Object * object = meshNode->EvalWorldState(time).obj;
GeomObject * geomObject = (GeomObject *)object;
Mesh * mesh = geomObject->GetRenderMesh(time, meshNode, *(View *)&nullView, needDelete);

 Then I read out the geometry data and save it in the renderer's specific storage.

Can anyone see where the problem is?

Thanks

you just need to make sure all proper notifications were sent to the scene objects prior to parsing, like BeginRender, Update, NOTIFY_PRE_RENDERFRAME, etc. Just copy the calls from cjrender example

Díky :),

I was missing the RenderBegin and RenderEnd calls on INodes. It's kind of unfortunate though that the objects with render-specific settings lose their cache and get rebuilt every time they make the switch from viewport to render and vice versa - this makes listening for mesh changes quite a tedious process as these rebuilds get in the way 😕
