Re: **** PLEASE POST ALL VFR4 PROBLEMS HERE *****

Vlado suggestion is for the wish to set an environment size, so that the user can set that the HDRI env match with the size of a room or an exterior size. The idea behind is, that a interior HDRI with infinite size create a wrong DOF effect. The suggestion should work fine for that usage.
But the suggestion isn't for the groundplane problem. I only can recommend to test the workflow of a environment mapped ground plane, it's a dream. Could be a favourit workflow for beginners and it could be nice if the DOF could work.

hi
sorry for my English I using a traslator

a very very serious problem in vray of rhino4 exists and is that it does not allow to rendering archives of but of 100mb if happens of 100mb it sends to message RUNTIME ERROR and the program is closed it is to say if I have a building and I must make 4 views and the building weighs 200mb I must eliminate everything what it is not seen in the Vista which takes to me to make a file by Vista single it passes me to my or it exists somebody but my PC is a AMD X24800 and 2gb of nonsingle memory in case it serves as something and also passes in my PC to friends him to past

My guess would be that you are running out of memory on your machine. Perhaps if you could send us the scene then we can figure out a solution for you - but without seeing it I can't help too much. Upload the scene to ftp://ftp.asgvis.com/incoming - you can just open that link up in your window's explorer and then drag your file into it. Don't worry if you see the directory as empty - anonymous users have write-only access there so you won't see anything.

After you've uploaded the file email me and let me know the name of it.

Re: **** PLEASE POST ALL VFR4 PROBLEMS HERE *****

Toady a bug riddle: set GI and background and reflection env at different colors and render a cube and save the image as png. What color is visible at the image background?

Answer: no color from the three colors - a grey background is shown.

It helps to use bmp or jpg - to less or to much compressed.

Re: **** PLEASE POST ALL VFR4 PROBLEMS HERE *****

...No bug...Pngs use an integrated alpha channel, so there is technically no color there.

Re: **** PLEASE POST ALL VFR4 PROBLEMS HERE *****

I know. Normaly my image viewer XnView ignore the alpha information and show me the background too. So, I copy and paste the image to photoshop and get the background. But today I got the effect, that the background is grey at XnView and greay and not transparent at Photoshop.

good I do not believe that it is outside memory because in task to manager the memory this underneath 2gb and that story with 8gb but for the equal memory swat but will send the file so that you observe it

thank joe

Re: **** PLEASE POST ALL VFR4 PROBLEMS HERE *****

If I use a "name" for a material, than I can not use the name again for a material layer. Additional a wish for that: could be good, if at each new material all used layer names of previous created materials could be used again.

Re: **** PLEASE POST ALL VFR4 PROBLEMS HERE *****

I'm not sure I post it befor: the Rhino material base on a wrong default setup, because Gloss finish 0 means a very raugh surface and that cause noise sometimes. So, if reflection should be disabled, than gloss finish 100% and gloss color black is better - than it's a simple diffuse material.

[joe_b]

Re: **** PLEASE POST ALL VFR4 PROBLEMS HERE *****

Sorry - I don't understand. The Rhino default material is wrong? Or VfR is doing something that is wrong?

[Micha_cg]

Re: **** PLEASE POST ALL VFR4 PROBLEMS HERE *****

If I use a Rhino material, than at default the glossiness is 0 (gloss finish) and the glossibrightness 100% (gloss color). This is a surface with 100% fresnel reflection and 100% roughness. Why calculate a 100% rough reflection, if a simple diffuse could do it better? I mean, per default should be the reflection so easy as possible, but now it's so difficult as possible - full rough reflection.

Re: **** PLEASE POST ALL VFR4 PROBLEMS HERE *****

Best post some examples/a scene because I'm just not following you with this one...are you having an issue with how rhino specifies their materials because we have no control over that...or is it in how those parameters get rendered?...I'm just lost.

[Micha_cg]

Re: **** PLEASE POST ALL VFR4 PROBLEMS HERE *****

...are you having an issue with how rhino specifies their materials because we have no control over that...

Ah ok. My suggestions is, that default settings for Rhino material should not be "gloss finish" 0 and "gloss color" white. I try to understand what kind of material this is. Diffuse? Glossy Plastic?

I tested to import several free 3ds models and see, that the gloss finish is allways 0, that means 100% roughness or? Interesting, my new tests show me now, that gloss finish 0 is no glossy effect. Thats fine. So it's my mistake to belive that 0 means 100% roughness. :-[

So, why did I post about this issu? My problem was, that I use some times objects and got noisy surfaces, because the Rhino materials support the glossy finish option, but not glossy subdivs. So, I'm back to old wish, that if Rhino material use the glossy finish between 1..100, that internal a good subdiv value is set.

[Micha_cg]

Re: **** PLEASE POST ALL VFR4 PROBLEMS HERE *****

I'm not sure I post it befor: if I copy an object with a 2sidematerial from one Rhino task to an other, than the sub materials are not copied.

Re: **** PLEASE POST ALL VFR4 PROBLEMS HERE *****

Any time I try to use a HDR image in GI or background, some strange artifacts appear in my rendering as can be seen in the attached image. The attached image is from one of Micha'a startscenes (2.3) with the associated visopt settings. I have checked my HDR files and they are ok and I have flagged off reflect caustics and refract caustics. If I do not use HDR images in either GI or background, the images render fine. Can anybody help explain what is happening ? Thank you !
