Rendering slow with Vray

vray

#1

model takes too long in building light cache in a test rendering of exterior


#2

What rendering program are you referring to?


#3

vray sketchup


#4

There are lots of rendering applications out there. You need to indicate which renderer you’re using when you post. I moved the thread to the correct forum, too.


#5

How long is too long? Please be more descriptive in what the render is doing. Maybe even upload a model screenshot and your vray settings.


#6

it has taken close to 3 hours now and its just test rendering option i picked from the preset option. the only thing i change in the vray setting was just the environment- background option to an hdri map

Maybe upload the model as it’s hard to say what’s causing the problem.

To try to narrow it down, I typically start by doing a materials override render to see if that helps.

Then I try a render with different entourage groups either turned off or saved separately and then deleted and purged from model…sometimes a model from 3D warehouse, etc has a bad material reference that can cause problems.

Next, save a copy of your model and reset VRAY settings to default. That may help indicate there’s a problem with one of your settings.

Once those are checked we can try other things.

There is also no information about Vray version (1, 2, 3 or 3.6).

Could also be you computer / SU version / Graphics card issue. Do you normally have fast renders and only this one is slow?
