(1) ... in 12.1 the bump dosn't work. If I reopen a material, than the bump is reset to "not in use".

(2) the increment of the QMC noise threshold chooser could be 0.001 instead the 0.1 at the moment

re (1): True, I noticed that in 12.1 "Bump" is unchecked when you check it, press Apply and return back instantly to material editor - but the bumpmap IS rendered although it should be off according to material editor.

Thank you Pif, good to know.

Question: what do the reflection color do? Today I have try to set a reflection color and I have got a transparent surface. I'm confused.

Center Bias: I have tested values from 0 ... 1000 and I can't see any effect. My scene is an arch viz in centimeter units. Does the option realy work or did I use the wrong parameters?

Reflection "color" is the intensity. Reflection filter applys a color to the reflection. I don't know how you got a transparent surface from using a reflection layer. You would have to send me the vismat or fully describe your material

I have try to create a metalic car paint - a reflective fresnel reflection layer and a colored blury reflection layer. I have try to set the reflection color at a dark blue, but the surface was looking like a transparent soap bubble - the blurry layer was nearly complete transparent. I have not used a diffuse layer behind all.
If I use the filter color instead the reflection color, it works fine. I feel, the current interface is not self explaining enough, new users could do the same error. If the filter color and the reflection color would exchange the names, I would feel better.

Well currently our interface doesn't say reflection color does it? I thought it just said "Reflection". I guess I could say Reflection Intensity, but switching them as is does not explain it correctly. I don't think "Filter" explains intensity, it explains a color, at least in my head. The tooltip for the reflection button even says "Choose the reflection intensity". However, I suppose other people may feel the same way. I guess we can rename it so the one is "Intensity" and the other is "Color" to do away with any confusion.

Your last idea sounds good for me. Only one problem I have - at renderman there was no difference between color and intensity and I see no difference. A color is a three dimensinonal intensity multiplier - RGB. I think, color and transparency could be the right names.

That is really what they map to yes, but your idea is backwards of which is which. Reflection maps to the Transparency and Filter maps to Color. Making a reflection value of Red does not make the actual reflection surface appear red. Putting the filter color as red does this. So then, in the UI I will replace "Reflection" with "Transparency" and "Filter" with "Color".

Output size bug: I set a custom resolution - 2000x6000 - and for some test renderings I disable the custon size per "override rhino" output. But, after my test rendering, if I try to enable the custom size, the size is reset to the rhino viewport size.

**** PLEASE POST ALL BETA 12 or 12.1 PROBLEMS HERE *****

Yes I'll have to re-wire how that works. Basically, the same variable is being used so if your not overriding Rhino, Rhino is filling in that value. I'll add a seperate variable to prevent this from happening anymore

Rotation of environment hdr maps is wrong by default and doesn't work as expected. The flip options are wrong imo.

I still don't understand the reflection and filter stuff. If color is only the intensity, why can you choose a color there? Why not simply a spinner with numbers? Or why not merge the color and filter in to one, like before?

Because now when you choose a color for reflection, things start to look weird. A red color for example gives red and blue reflections...

I'll play around with it

We never had it where they were merged together. Before I simply did not allow a filter color to be used - it just wasn't hooked up. The "Reflection" hooks into a variable named "transparency" in the actual BRDF plugins. It has always been hooked into that same variable since Beta 1. As to why it is a color? I guess you would have to ask Vlado why its a color. The "Filter" maps to a variable named "color" in the BRDF plugins. Naming it "Filter" was a suggestion I took from Vlado, he said thats what he was/is calling it in the new VRay for Max IIRC.

This subject, I suppose, is beyond my ability to explain since it seems I have only succeeded in confusing people futher. I'll see if Vlado can maybe post to clear up the questions you have with what the purpose of these two things are.

It's a early bug - No 005 - at my list. Joe, I hope you look at my collection list from time to time and don't forget one.
