DR gives me headache!

[Timbur]

I got weird problems when rendering. First render is fine, everything looks great. BUT then if I change something like view, background etc. the second render looks kinda wrong. There's pieces of that first rendering.

 

I use Irrmap for primary bounce and lightcache for second. And I think it's the irrmap what causes problems because when I changed it to bruteforce render was fine. Also booting nodes helps but who wants to boot them after every render?

 

Second problem isn't because distributed rendering but it's weird too. When I have image or vraysky on the enviroment slot, you can see them through shadows.

 

So please, if anyone knows how to solve these problems just let me know, thanks...

could you post an image of the problem with the shadows?

 

The issue with the LC sounds like the machines are holding on to the LC somehow. I would first make sure that your LC is set to single frame and uncheck don't delete and save file. If that doesn't work I would maybe try making a seperate file for each camera and see if that helps.

I don't think it's the LC what causes problems, because LC pass is always OK. Irrmap is where the problems appear. But maybe it's the settings, I try to uncheck those "Don't delete" on render end.

 

For that other problem... Here's a pic from LC pass and you can see that sky and that tree is (don't worry about the scale of image, it's a test ) showing through the building. And it shows in the final rendered image too.

Are you by any chance using your background image in VRays GI environment override slot to light the scene? I remember one time I did this it actually projected the image onto my model.

Other than that, I'm stumped...

This was happening in previous releases, ( but I think it was fixed in 1.5 and up)

 

We used to turn incremental save OFF when rendering in DR,

 

Use the cam you want to render > hit save > then render with DR, should get rid of the squares that are from the slave computer, from the previous save of your drawing.

Thanks guys from replies. Must try those things rightaway when I get to work. Somekind of script what boots the spawners before rendering would also be great.

You can run spawner on the slaves machines as a service, so the actual user of the machine does not see it, and it is always ready for you when wou need it.
