Viewport redraw on material change in MatEd - necessary?

[pokoy]

I am seeing viewport redraws when manipulating/assigning materials or maps in the material editor even if the material is not used on any object. This happens ONLY when Corona is assigned as material editor renderer, if Scanline is used in the MatEd there will be no redraw.

I am not really sure if it is intended or necessary, maybe it's a side effect of some IR data being active 'under the hood' all the time...? Whatever it is, it is really slowing down working with materials in general and should be avoided if IR is not active.

Hi, what exactly do you mean by viewport redraws? Do you mean for example that AO restarts when using "realistic" viewport mode? When does this happen? When adding any kind of map to a material?

Which version of 3ds?

Max 2016 and Nitrous viewports.

No, what I mean that the normal viewport will redraw, in 'shaded' mode. I guess you'll only see it when the model is heavy, anything else will be probably too fast to notice. It seems that Corona is constantly 'aware' of the viewport for some reason (or the other way around) and material changes will affect viewport for whatever reason.

It happens for me on:

- adding a map to a material (either by dragging from another mated slot or by adding through the mat/map browser)
- assigning a new material to a slot (through the mat/map browser)

This happens on both used and unused materials and maps.

moving - reason: old, inactive
revive if needed

old/inactive, lots have changed since then

Yes, not relevant anymore. Thanks for checking!
