I have a big problème with my scene.
I’m modeling an house, so i allready done bedroom, living room and kitchen.
Now i’m trying to render differents views from cameras.
To tchek luminosity i hide all elements and try to render in 640x480 but after 10min Corona still calculate illumination ! I mean render screen stay black (except four-five white small points).
I allready done some renders before and i never get this probleme.
So there are my questions :
if i hide all objets before render, corona calculates them even if they are hide ?
how can I do to only calculate objects in my camera field ?
Just check what current task in rendering dialog, to be check if it’s rendering or making preparation for rendering. And check you ram usage, is it enough for your scene? And double check light =)
Hi Spray. Thank you for your contribution.
I found the problem : I removed all displacement maps on basic wall texture.
And Screen Size was set on “1”
On my laptope (currently im working on my laptop waiting for my work station back) i have a warning message about RAM. But as i said in my post I allready done all previous render with these warning messages.
Anyway now, without Displacement map on the wall i can make render (8h for 1280*900…a kitchen viz … I know it’s creasy but usual with this laptop ah ah !! )
That was the problem. My basic wall material had displacement map. Evenif i only rendered the kitchen, my house wall with displacement was calculated.
I removed displacement map on wall texture and now it’s ok !
It’s best to use bump for small, fine details, and displacement for large features only.
Think of a brick wall:
Bump - cracks, scratches, surface structure
Displacement - brick pattern
And when using displacement, rarely do you ever need to go below a screen size of ‘1’, as lower values are essentially creating edge lengths of tessellated geometry that are smaller than a pixel, which is mostly unnecessary.
Hello everyone, I need help with slow rendering too. I need to render a huge image for the poster, so resolution set to 5906x4724 and rendering is very slow for some reason, also CPU is not loaded at all. I’ve searched some info about low thread priority, but there is no option like that in Corona 1.5. I used to render the same scene couple of months ago in 2000x1500, and it took me 1-2 hours for 50-60 passes, CPU was loaded with 70% and more, and now it’s only 5-10%. Any solution for this? Also, i’ve set 3dsmax.exe to real-time priority
