render speed test

[blendervrayf]

Today before to install version 3.3 of vray I rendered an image.

render time 4min 46 second.

After I installed vray (330049) and I also installed the latest version of Blender and updated the exporter

result; 5min 19 sec ...

what happened??

I had read that I would have a reduction of render times, but the opposite has happened ....
any suggestions ???
thank you

It's difficult to say without a scene; can you post it here or send to support@chaosgroup.com?

Best regards,

I can not post the file that I used in the test because private end unfortunately I did not have made other test render.


why the screenshot says vray 3.25.01, it is correct?

when I installed the latest version of vray I have not uninstalled the old version but I do not know if this is the correct procedure

[blendervrayf]

some idea?

[blendervrayf]

Hi
I uninstalled and reinstalled vray.
Now I note the following issues;
1 at the bottom left corner there is no longer the indication with the vray version and render time. ( pressing the apply button stamp)
2 sometimes in scene the material change settings
3 the mash light material does not work anymore.
could you tell me what has changed to create a mash light.

thank you

1. Fixed with https://github.com/bdancer/plugins_d...1f3a93b9ef7fa8
2. Sometimes?
3. Fixed with https://github.com/bdancer/plugins_d...3887a84c95f86f. You could also uncheck "Disable Self-Illuminatino" under Globals.

Btw, Light BRDF is not a mesh light:

Hi and thanks.

2;
sure, this morning came out 2 different render without changing anything in the scene. It is not the first time it happens. Now I downloaded the latest version of blender_vray .. hopefully good ..
Also today, a duplicate an object and I modified slightly (deleted a part thereof). In the render he gave me a completely different result compared to the original. I checked texture mapping 10 times and was perfect mapped so I did this operation several times end the material looks always incorrect.
I really do not understand ...

3
I remember a light object as attached. Maybe I do not remember very well.....

2. So, what are the changes? How could I reproduce it? I've recently changed a lot of default values for all V-Ray plugins.

[blendervrayf]

o yes with the latest version of blender Light BRDF works as before ... thanks (until yesterday he created a black material also enabling GI)

2; I 'm not able to reproduce the error ..next time I will attach the file.

at the link there is a blender file to download. Can you tell me yours calculation times.I would compare my results with yours. http://dropcanvas.com/vjm2m
My pc i7-4771 cpu 3.50GHz 16GB

Many thanks

Hello..
I ask the friends here on the forum if you have problems like me.
the situation is quite frustrating since I installed the latest version of vray and blender.

I have the following problems.
* I works all day long on a project and then suddenly changes the final render (usually after a crash).
FOr example Tuesday in a project he always render a yellowish image (I thought it was the inclination of the sun). then crash. In the evening I open blender and blender render a clean image how I wanted .Last night blender crash so I restart blender and press f12. the image is yellow again. Today crash and the image is ok .

Because crashes ?? usually when I start an animation end blender stop to work.

BDANCER asked me a file but it is useless because the file may work properly (then there are the texture and do not know how to attach them at the blend file)

Finally today I downloaded the latest version of Blender and does not update the exporter ...

oooo .. what's going on ...

[bdancer]

blendervrayf, nightly builds are called nightly because they could contain issues. Use stable versions then.

[blendervrayf]

I didn't know.
I thought they were updates.

[bdancer]

Official updates are uploaded to the main website http://www.chaosgroup.com/en/2/index.html.
And we'll find out the reason of the slow down.

[blendervrayf]

thanks for support

I downloaded the official version from here http://www.chaosgroup.com/en/2/downl...=v-ray-blender Blender2.73
and I turned on vray render.
*The problem is that the materials remained always blacks even in preview.
So I re-installed a version that I had previously used without problems (2.74-4).
Now everything seems to be working well. The animations are successful and the images are consistent with the settings.

About the render times;
the file that I posted was rendered in 2 minutes and a few seconds while yesterday more or less 10 -11 minutes.

The old file (the one with grass) in 5 minutes and 3 seconds while the render before installing the latest version of vray in 4; 46 seconds ... but ..... I notice small differences in the final image. Maybe when I took the file to make the first test I increased some parameters in GI.

so I'm sorry for the whole situation, but I thought that by downloading the latest version was doing the right thing

thank you very much
