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

Hi Joe,

I've reinstalled Vray, but the problem still exists.

It only happens when Vray is set as the renderer. Even if Vray is installed, if I chose Rhino as my renderer, everything is fine; I can see the light properties.

Tonight, I crashed few times when I was switching between the two renderers, and clicking to see the light properties of few test lights I placed as experiments.

I have not gone through everything Vray offers, but it seems Light Properties is the only window effect by this.

It does feel like it is a UI issue with Vista. I've also noticed that the closing box on the top right corner of windows are tiny, as you can see on the picture I posted previously. This is common for all windows within Rhino on my Vista machine, not just the Light Properties window. Is this part of the issue?

Re: Material Editor - importing packed materials into Rhino.

I have just created a large amount of materials using the material studio which has worked quite well.

But when I transferred the materials onto another computer and tried to import them into Rhino I realised that all of the linked bitmaps were not working. On closer examination I noticed that they were trying to link back to the address of the original bitmap, not the map that was created when the material was packed. When I import the same material into the Material Studio on the new machine everything was linked and worked correctly.

Has anyone else been having this problem?

Ok, I just tried copying the materials across a second time, this time it works fine. Not sure what was causing the problem!

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

* I'm working on a scene with textures in three dirs. I decided me to use DR and copy all textures to the project texture dir and copy the whole project dir to the same place at the slave. I thought, the Rhino texture search code try to find all textures at the project texture dir, but the slave try to open the textures in the old dirs and dosn't try to to search in the project dir.

* I setup a VraySkp2SideMtl for a material with invisible backside. The first material is a plastic material A with own reflection env map (black acolor) and the second material is transparent (I set the same refl env). If I render material A, the refl env of the material is used, but if I use the VraySkp2SideMtl, the refl env setting is ignored and the global env is visible.

Did you copy the materials into the same spot both times?

I suppose it could be the same issue. I'm looking for a redistributable that contains all the UI stuff we utilize and I'll contact you via PM when I locate it.

Thank you Joe, I will be waiting,

(edit)

Thanks Joe, and the whole team, I got the problem fixed with the new patch!

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

I try to use a env image from

http://www.flickr.com/photo_zoom.gne...723@N00&size=l

for texturing a large grass area and wonder me, that I lost so much detail of the nice high res texture. I disabled the image sampler filter and the texture filter, but nothing helps.

Hi Joe,

When it worked I did have it in the same location (same account on the desktop of a stand-alone windows XP setup). When it didn't work it was on my desktop at work, but the desktop is setup on a linux server so that may have caused some issues.

I thought the whole idea of packing the material was so that vray knew to look in the same folder as the .vismat material file was located. So therefore making it independent of the wider folder structure?

How else can I transfer my materials library from machine to machine (maintaining all of the links) on a standalone machine or one that is included in a business server setup?

The materials downloaded from the materials section of this site seem to work no matter where I put them? Would zipping them before transfer make a difference?

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

Micha,

You may want to adjust the antialiasing of the textures. You can do this by changing the Adaptive Subdivision (Color) Threshold from .1 to something like .075 or .05 (sorry, can't do this in AQMC or fixed rate). Try that and see if that helps. I don't see why it wouldn't, but if it doesn't, it may be do to the environment mapping (similar to the environment mapping w/ DOF thing you stumbled upon earlier).

EDIT:
Yea, I ran through a few tests and the color threshold doesn't really work for this. Here's the thing...the original texture that you had in your grass post produces good results, and the new image that you posted today has worse results. I think the resolution is just not as good on the new image as the old one (the old one was much bigger and you had repeating 9 times). There's no telling exactly how many pixels from the image are used for the image, but once I repeat the flicker texture 2 or 3 times, there is much less blurring horizontally (vertically it can't be repeated, so maybe some photoshop and I'll be back)

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

Damien, if you compare the distance between two striking points, like two flowers, in both images, you will see, that the scale is approx. the same. I remember me on a blur texture bug some months befor and Joe fixed it (it was a memory usage texture issue). Maybe it's the same here. Or Vlado could help. It's a pity, if a high res environment looks like a lower res one.

No - zipping them shouldn't matter. At this time VfR looks at the absolute path that is referenced by the material - then it looks in the folders around the Rhino file. So if its anywhere around there it will find it. In our upcoming service release we will also be adding the directory of any imported vismat to the resource search path.

Today I open my test scene and .... the rendering looks fine, the extrem blur is gone. ;D

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

And here an exotic bug: I use a 360° jpg env texture for a groundplane and enable DOF. The focus is at the head of the frog. Bug: the frog is sharp, the groundplane blur (screenshot show the groundplane isocurves and the ground texture without DOF is perfect sharp).

It seems to be, I'm the only one how think it's a bug. This is a bad news for me, because it could be so easy to use high res environments. So, I can use my 10.000x5.000 HDRIs without DOF only.
Or could this feature implemented per VfR plugin - an object-camera-distance based DOF allways? My dream is the easy-to-use-full-HDRI-environment.

Was there a problem with Vlado's suggestion to map a sphere instead of a groundplane? Also - I will look into the camera mapping stuff to see what kind of work that will require.
