Hi Paulo, thanks for response! I have replied to PM too btw.

These drawbacks go to the todo list. What this object tag has to do? There are so many opportunities to place there like making priorities for material inheritance in the hierarchy of objects and placing priority for different displacement shaders attached to instances of one only object.

As I understand the Film Offset is a more general trapezium in world space used for camera instead of rectangle?

Do you mean that it's black when IPR not working? I know about it and need to fix some things to make previews always working regardless of IPR.
Or is there some other problem?

1) Ok
2) Do you need separate resolution control to be enabled in IPR?
3) Not fast enough? We made it lower quality than in Octane and Corona, but faster. Maybe there is some bug, lag, need to see.
4) Ok
5) We have it if Transparency roughness = 0. It basically works as is: the rays starting from the camera to the first diffuse hit are refracted, and then they work with IOR = 1 (no refraction).
6) There is control of production render iterations (see page 9 in user manual). However it works for everything: for render region, viewport and picture viewer. Probably need to separate these controls. Also there probably need to make time limit as alternative to the number of iterations. And I think there can be confusing thing with "number of iterations" vs "number of samples/pixel" which may differ for given number of iterations and different resolutions. Need to clarify this.
7) Do you want to have an informational status bar on Picture Viewer? There is currently just a small stupid green progress line. Also need to make a status bar for scene loading process.

Ok, this is all can be done.

As for Tex vs Shader - that's inheritance from common parts with plugin for Max.

Well I know that it is sometimes black (when IPR is not working). If you start IPR then it should update with pictures. It will be fixed. There are also no previews for some kinds of shaders like binary, falloff, blend. Will need to accelerate it too. So, it doesn't allow to move sliders smoothly as usual? I think it's image buffer priniting operation, will look deeper.

We will introduce certain optimizations to the core that increase convergence. There very promising results in our research tests.
Right now will not make somebody more nervous about this because we undergo hundreds attacks everyday on this site since publishing alpha for Max. Need to see how to backup the site just for any case.
