Btw, it's time for the new splash =) Post your variants here.

Re: V-Ray/Blender 2.57

Request:

- Most time consuming is UV unwrapping all geometry; is it possible to add the Blender function 'global mapping' for image textures + projection options?
- Could you add a function for rounding corners as a material option. (as found in Mental Ray)

Bug:

- When using the array modifier in combination with an instanced object, render result goes wrong when instances have other counts for the array modifier.

Re: V-Ray/Blender 2.57

Use Object mapping, it has projection options.

When using the array modifier in combination with an instanced object, render result goes wrong when instances have other counts for the array modifier.

Its not a bug - this is how it works. Array affect mesh; disable Instances option or use Shift+D for duplication in this case.

Could you add a function for rounding corners as a material option. (as found in Mental Ray)

Mental Ray? =) You mean V-Ray For Maya? Ok, I'll add this.

I actually meant Mental Ray, since I know it has this feature. I don't know about Vray for Maya. Sorry for the bad language though

Re: V-Ray/Blender 2.57

Hi Andrey!
Some days ago i was tested unsymmetrical ies light in yafaray and vb after Dialux rendering.
This ies must imitate 1 meter tube LED lamp.
I have found, that vb give me incorrect result - can U test it?
In atachment blend file, yafaraj rendering and ies file.
...too big archive...
Ok - only render and ies file in atach.

Re: V-Ray/Blender 2.57

Yaroslav_L, so what is incorrect? Why do I need yafaray rendering? May be yafaray rendering is wrong?

[Rchv]

Re: V-Ray/Blender 2.57

Use Object mapping, it has projection options.

Wow that is great, I tested it in the 35732 build and works perfectly for archviz, huge time saver from UV unwrapping.

Re: V-Ray/Blender 2.57

Andrey - I was write: "I have found, that vb give me incorrect result"
It's not interesting for U?
And I attached only YaR render, because I wasn't save image rendered by vb.
But... Ok.

I just don't see any incorrect stuff in this renders.
Its interesting for me, but you need to prove it. Saying "here is yafaray render its different from vray" is not a prove of anything
Could you post a photo of this real lamp and render of its IES?
For me the renders you show just differs in color mapping settings (which cause different color burn).
Anyway exporter just exports params =) If you think its a V-Ray bug - please, report it to ChaosGroup.

Re: V-Ray/Blender 2.57

Ok, sorry. I just try to help in that way...
And yes - I think vb give me incorrect result - like from big bulb lamp - not tube.
Yafaray ies representation looks better, but I like vb night environment...
And one more question: what is correct physical camera settings for that night shoot?
Thank U.
P.S. Tube fixture:

Re: V-Ray/Blender 2.57

Hi, I looked at that also..
I think the IES data behaves correctly. It also reacts to light transformations (rotation).
I came to an idea that maybe the possibility to scale the ligtht together with its propagation limits (ies) would do good in such cases (linear lamps).
Andrey, do you think this would be sensible/possible to introduce such transform factor to lamp parameters?

Re: V-Ray/Blender 2.57

Yaroslav_L, your help is much appreciated =) I'll check this IES file.

Re: V-Ray/Blender 2.57

There are some override params for length and width of IES (by default everything is taken from IES file) - I could add them in UI.

Re: V-Ray/Blender 2.57

Hi Yaroslav,
I just wanted to ask U if these different results (yaf/vray) with IES arent caused by different shutter settings in physical camera?
I mean does shutter speed shouldnt be longer to achieve result from yaf renders?

Re: V-Ray/Blender 2.57

I am working with the FastSSS material now (which actually implements VRay's FastSSS2 material, so maybe the name inside Blender should reflect that).

The texture assigned to "Overall" doesn't get assigned. This is probably related to the fact that the "Overall color" doesn't work too.

The Subdivs in the Specular layer properties and the Single scatter properties are limited to 10 - not only the sliders, but any direct input above 10 gets reverted to 10. I don't see any hint in the VRay's online docs that this is an internal limitation, so this may be a bug.

In the influence tab there should be a separate field (checkbox and slider) about assigning a texture to the scatter color, besides the existing scatter radius multiplier. The results with the same texture assigned to scatter color and to scatter radius are different (tested), and the docs state that they control different values, so they should be implemented separately.

This is for now. Greetings!
