V-Ray/Blender 2.5

[bdancer]

Re: V-Ray/Blender 2.5

The material preview is very awesome

Glad you like it =) There is a little bug in blender itself (actually preview render is called 3 times) and I'm waiting to svn changes of how to avoid this.

I think the cube, Suzanne, ect. are on your todolist?

Yes, but not for the coming changes. May be for release.

Is there a checkbox, to leave the VFB open, after rendering

In latest git - Image to Blender. If its off - image will not pass to blender and windows will stay opened. I will add more accurate controls for this.

The (pre)view in VRay is much darker than the result in Blenders render window.

This like blender loads EXR files. There are no additional options to control which gamma to use on image load. In latest git there is a support for image type control so you can switch to RNG for example

There is a "active Layer" button, could there also be a possibility to choose which layer to render. (I often disabled not needed layers for modelling and forgot the enable them for exporting)

Hm, i think i'll create a smth like menu - use all layers, use active layers, use defined layers.

Integration of render slots, for easy comparison

Yep.

when I want to see the result of the render, but closed the render window (in blender, by pressing ESC) during the render, the image is lost. Render > Exit Blenders render window > Vray has finished the image > switching to render window > Image lost.

this is because changelog:

render image is automatically loaded to Blender (and Esc now stops render and close VFB window)

When rendering some 2.5 files (from Blenderguru) I get: AttributeError: 'NoneType' object has no attribute 'name'

I need to see this scenes to find a bug, could you submit some links?

Cool.

You mean a command line option?

What are RNG images? I can't find useful information about them

Perfect

[/quote:2cu5alo0]Oh I thought you mean pressing ESC in VFB. But VBF is not closed, when I press ESC. It would be cool to be able to do both, leave the render window to adjust settings, ect. and to be able to quit the render by pressing a button in Blenders render window.

PNG =)

>>You mean a command line option?
I mean smth like autoclose VFB: on/off (becase this autoclose changes Esc behavior - to stop/notstop render process)

Re: V-Ray/Blender 2.5

Thanks for the info.

I have compiled vb25 via your autobuild script. It works very well, no single error here on Linux 64bit. The .blender dir is in the applications dir, that's very cool. Now I can use vb25 and my normal 25 builds. But vb25 build much faster?!

Notes:
- I can render without "Image to Blender" checked, and when I check it after the render is finished, the image is loaded. Nice if a change my opinion after rendering
- Where can I change from exr to png? As I see png is now default, and it looks nice.
- Is there something you want tested specifically?
- The export speed is amazing.

>>Where can I change from exr to png? As I see png is now default, and it looks nice.
You could select file format in "Output" panel (tab, rollout - don't know how its called in 2.5 .

>>The .blender dir is in the applications dir, that's very cool.
I dont think its used by now. All settings are stored under 2.53/config and all scripts under 2.53/scripts/.

>>Is there something you want tested specifically?
Too much missing features - i guess some real testing will be required in a couple of weeks.

Oh, to obvious .
When I choose OpenEXR, the images are not passed back to Blender.

>>I dont think its used by now. All settings are stored under 2.53/config and all scripts under 2.53/scripts/.
Sorry, I mean this directory. I mean the separation of the /home/maces/.blender dir.

>>Too much missing features - i guess some real testing will be required in a couple of weeks.[/quote]
Ok.

Some other Notes:

- Material preview doesn't update, when I change the Reflection color.
- I reproducible crash Blender when I render only a part of the image (shift+b) and the rendered image is passed back to blender. When starting blender from gdb, Blender itself doesn't crash, it freeze:

This is blender api issue - bl_preview doesn't called when changing user-defined python props.

Accepted.

Yep, pasteall.org will be better.

Re: V-Ray/Blender 2.5

Hello
OS - openSUSE 11.2 64bit
V-Ray/Blender 2.5 (2.53.0 r 30716M)

I have a problem.
Yesterday I made symlink
ln -s /home/lolko/vray/vray/bin/vray /usr/bin/

/home/lolko/vray/vray/bin/vray - this is a path where i installed vray

When I made this symlink everything works fine (for the first time with blender 2.5 ) i rendered test ladder etc. I shut down computer and go sleep. Today i don't know why, nothing works and terminal show me this:

Traceback (most recent call last):
File "/home/lolko/Pobrane/vb25/2.53/scripts/io/vb25/render.py", line 2643, in render
process= subprocess.Popen(params)
File "/usr/lib64/python3.1/subprocess.py", line 639, in __init__
errread, errwrite)
File "/usr/lib64/python3.1/subprocess.py", line 1139, in _execute_child
raise child_exception
OSError: [Errno 2] No such file or directory

This look like i don't have a symlink but in my /usr/bin folder there is vray.

Could You help me and explain what I make wrong ?
Aha I have another question:
Could You make in Your script for blender 2.5 like in script 2.49.12 where I chose from system tab path to folder with vray bin ? This is for me very clear and I don't have a problem with vray/blender 2.49.12.

Thanks for Your work. You make a great work.
Greetings

My build and from djs_core's repo?

>>Could You help me and explain what I make wrong ?
Are you using V-Ray For Maya demo? If yes - check NOTE section here: http://wiki.github.com/bdancer/vb25/installation

>>Could You make in Your script for blender 2.5 like in script 2.49.12 where I chose from system tab path to folder with vray bin ?
No, I prefer fixing bugs and bug-reporting (like this vray bug with incorrect environment) to make everything better =)
Its much better if you just install vray and exporter and they start working together - so lets better find out why its not stating at your system.

Re: V-Ray/Blender 2.5

Thanks for Your quick answer. Now after Your help everything works fine
>>My build and from djs_core's repo?
Yes

>>Are you using V-Ray For Maya demo? If yes - check NOTE section here: http://wiki.github.com/bdancer/vb25/installation
This me help. Exactly this:
NOTE: there is a bug in V-Ray Maya Demo installer on Linux – incorrect environment variables.
Remove strike-out lines containing VRAY_PATH from files /etc/profile.d/chaos.sh and /etc/profile.d/chaos.csh:
/etc/profile.d/chaos.sh
export VRAY_FOR_MAYA2008_MAIN_x86=“/usr/autodesk/maya2008/vray”
export VRAY_FOR_MAYA2008_PLUGINS_x86=“/usr/autodesk/maya2008/vray/vrayplugins”
##export VRAY_PATH=“${VRAY_PATH}:/usr/ChaosGroup/V-Ray/Maya2008/bin/x86/vc6”

/etc/profile.d/chaos.csh
setenv VRAY_FOR_MAYA2008_MAIN_x86 “/usr/autodesk/maya2008/vray”
setenv VRAY_FOR_MAYA2008_PLUGINS_x86 “/usr/autodesk/maya2008/vray/vrayplugins”
##setenv VRAY_PATH “${VRAY_PATH}:/usr/ChaosGroup/V-Ray/Maya2008/bin/x86/vc6”

Thanks for Your help, suggestions and explain for my question about path to folder with vray bin. You are right. Your solution is better.
Thanks again and Greetings

Re: V-Ray/Blender 2.5

Dear Anderyme!

I am so glad the 2.5 exporter! My problem is that when I hit render, Vray starts rendering normaly but it always renders a black screen, and nothing else. There is a problem in the console(picture). Please help!
thank you

Re: V-Ray/Blender 2.5

@nieghel, update script and try again. If its wont work than update build (if you compile it with my script) or wait while I update builds.
