irradiance map problem with Animation(prepass) Mode

[sersia]

Hello,

I am trying to make a .vrmap with Animation(prepass) Mode. If I render Animation with that mode, V-Ray looks like working very well to make a .vrmap for animation.
But it doesn't save the .vrmap for Animation at all. I am using this build - vrayblender-2.60-42307-windows-x86_64.

One more thing, I am trying to use V-Ray proxy for the object of particle system.
Here are three images for understanding the setting and the idea.
Cube is used as Proxy. The proxy is Monkey that is subdivide 5 times, so that it has Face: 503809 Mem:290.05MB just for 1 Monkey.

I am using the proxy for particle object.

It is working great with single image like the below render Image.

But if I try to make a .vrmap with Animation(prepass) Mode, it doesn't work at all. Blender calculated something for each frame but V-Ray Frame Buffer didn't show up at all.
V-Ray Frame Buffer showed up with Animation(prepass) Mode if I didn't use proxy with particle even if it didn't save .vrmap as I mentioned fore-part.
BTW, it didn't work when I just render Animation with single file Mode for the proxy setting as well.

The idea is using proxy file for high polygon object to reduce memory usage for Rendering. It is quite useful feature for the crowd simulation scene.
If you don't mind could you check the problem?

I really appreciate it for your kindness in advance.

Re: irradiance map problem with Animation(prepass) Mode

Have you enable "Calcualte GI only" in "Render" panel and "Auto save" in IM settings? Check if "lightmaps" directory exists in scenefile directory (auto creation of this dir will be added).

Yes, I've tried to enable "Calculate GI only" for the testing as well. But normally V-Ray just calculate GI only with Animation(prepass) Mode even if I don't enable "Calculate GI only".
And Yes, I've enabled the "Auto save" as well. There is "lightmaps" folder but there is nothing in there.
I can send the test blender scene file if you need it.

Thank you.

Re: irradiance map problem with Animation(prepass) Mode

Sorry for disturbing you. It is working very well after I update Exporter. And I tried to make the path sure to save IM file.
Blender calculated all animation frames first when I render animation with particle object. After that, V-Ray is working. There is no problem to save IM file.

BTW, I think it doesn't work well with the proxy as using particle object. Because V-Ray got more than 16GB RAM to render the animation.
V-Ray take more RAM if there are more particles even if I use V-Ray Proxy.

Thank you for all of your help. I really appreciate it.

I've rendered 20.000 trees of 70.000 faces each with proxy on 4G RAM without any problems. But it wasn't animation.
Do you have a chance to compare it with the same scene in 3ds max, for example?

Hi,
Thank you for your fast feedback.

Yeap, there is no problem if I render just single image. But it still took more than 3.23 GB to render the single image.
And I got .vrmap with Animation(prepass) Mode but I couldn't get the final image with Animation(Rendering) Mode. V-Ray Standalone used more than 13GB(1-50 frame) to render the final image and it didn't work for the final image. It was more than 16GB for 1-250 frame.

So I tried to use V-Ray for Maya to compare with V-Ray for Blender. Using same proxy as a instance with particle system of Maya.
It is working very well. And Maya just took around Maximum 1.8GB to render the final sequence images for Animation.

As I mentioned, V-Ray Blender took more than 3GB to render the single image. But V-Ray Maya just took around 1.8GB to render the single image or sequence images. V-Ray Maya used Maximum 1.8 GB regardless of the amount of proxy object.
That said that V-Ray Blender use more Maximum RAM with the same proxy.
Actually the Maximum RAM might be similar between Blender and Maya regardless of the amount of proxy object in the scene. Because I just used one proxy.

Please let me know if you need additional information for that.
Thank you.

Re: irradiance map problem with Animation(prepass) Mode

Check "System" panel settings in Blender and compare them with Maya ("Settings" panel in render options), if they are different make them equal and test again.

This settings affect RAM usage (http://www.spot3d.com/vray/help/maya/15 ... system.htm):

Max tree depth - the maximum depth of the tree. Larger values will cause V-Ray to take more memory, but the rendering will be faster - up to some critical point. Values beyond that critical point (which is different for every scene) will start to slow things down. Smaller values for this parameter will cause the BSP tree to take less memory, but rendering will be slower.

Min leaf size - the minimum size of a leaf node. Normally this is set to 0.0, which means that V-Ray will subdivide the scene geometry regardless of the scene size. By setting this to a different value, you can make V-Ray to quit subdividing, if the size of a node is below a given value.

Face/level coef - controls the maximum amount of triangles in a leaf node. If this value is lower, rendering will be faster, but the BSP tree will take more memory - up to some critical point (which is different for every scene). Values below that critical point will make the rendering slower.

Dynamic memory limit - the total RAM limit for the dynamic raycasters. Note that the memory pool is shared between the different rendering threads. Therefore, if geometry needs to be unloaded and loaded too often, the threads must wait for each other and the rendering performance will suffer. This also controls the memory limit for tiled EXR files with mip-maps. Geometry and EXR tiles will share the same memory pool.

Note: Dynamic memory limit = 0 in Blender means "auto".

You are totally right. I forgot about it. Now V-Ray Maya got similar RAM(around 3.23GB) to render single image or sequence images.
But I couldn't get sequence images with Animation(rendering) Mode for V-Ray Blender. It took too much RAM with Animation rather than just rendering single images.
Do you think I am missing something else for that. It is hard to figure it out for me. Maybe it is from blender's particle system? hmm.

Thanks once again.

Re: irradiance map problem with Animation(prepass) Mode

Hello again,

I got more test. And I got this result.

Firstly, I got this short video. - http://youtu.be/cUi5iZTP3U4

The proxy is working with Animation if I don't use Animation(prepass) and Animation(rendering) Mode. But it took too much RAM for Animation Rendering.
V-Ray just took around 3GB RAM for the same single image Rendering. But V-Ray took around 13GB RAM for the Animation Rendering even if I used V-Ray Proxy to reduce the usage rate of RAM.
If there are more Monkeys with lone frame, I couldn't render all Animation with my 16GB system RAM even if I use V-Ray Proxy.
But it just took around 3GB RAM for a single image rendering even if there are plenty proxy monkeys.
Look at this. what a lovely plenty of Proxy Monkeys. it just took 3GB RAM when I rendered a single image. but it took around 13 GB with Animation Rendering. So it is weird for me.

Secondly, I got an error when I tried to use Animation(prepass) and Animation(rendering).
I got this error with Animation(prepass). This message came out when I've used Animation(prepass) Mode with plenty of Proxy Monkeys. And V-Ray stay with the 13 GB RAM until I quit Blender.

And I got this error with Animation(rendering).
[attachment=1:1hzy1gye]vrmap.jpg[/attachment:1hzy1gye]

BTW, V-Ray Blender's Animation(prepass) and Animation(rendering) Mode are working great with normal scene. It is just happened with my uncommon scene. I think it Needs more test to figure it out.
It looks like that the problem is from Blender, not from V-Ray Blender.

Thank you for your help.

These IDProp messages are from Blender not V-Ray.

It is just happened with my uncommon scene.

Could you send it to me then?

Thank you very much.
I sent an e-mail to you with the scene file.
from alixs@hanmail.net

You can download it from the e-mail server. Please let me know if you have any problem to download the file.

Thanks once again.
