- set the output to the small size, the rendering is finished Light Cache and Irradiance steps, turn it off and save the Current Map of the LC and IR, then you use this map for the render times with larger image sizes without having to wait …
Hi tranganhhp
I am only having a chance now to study the model you supplied. I have learnt a lot already
I was reading over you post again and am uncertain about what you mean in the quoted text above. Can you or anyone explain this a bit better perhaps? Be greatly appreciated
Anyone?
You could save the GI solution (Irr and Light Cache) for a small image and then use that solution to render the same view, but for a largest image. If you use a saved solution, V-Ray will not calculate the GI, because you are using a pre-saved one, instead V-Ray will go directly to the final render. The general recommendation is save the solution for the half of the final size. For ex. If your final render will be 3000dpi x 3000 dpi, you could save the GI solution for the half of that size (1500 x 1500). And use that solution for the final render at 3000 x 3000 without losing any details on the render.
On the Irr Mode you have to select “from file” for the final render and then call the pre-saved GI solution using the file picker.
Yes think also that I don´t understand very well too ???,…i agree with jarynzlesa, don´t exist anywhere one tutorial with step by step! this is one theme very important to us.
if i understand your problems correctly… fernando is trying to show you how you can cut down on calculating times for illumination with irr map, light cache etc etc.
1. GLOBAL SWITCHES in OPTIONS EDITOR and tick/check DONT RENDER IMAGE.
2. Set your irradiance maps and light cache settings
3. Set the OUTPUT size to half the size that the final render will be ei if you want a 3000px wide image set it to 1500px. You can make the size a quater but it may cause undesirable effects.
4. RENDER - you should see Vray fly round as normal, but it will not render the finished image. Once finished…
5. OPEN the OPTIONS EDITOR
6. Under the IRR MAP (If thats your primary engine of course) you should see at the bottom of the roll-out a sub-title called CURRENT MAP with 2 options SAVE and RESET and some data figures to the right.
7. Click SAVE and save this file to somewhere you can remember.
8. Repeat steps 6 & 7 for the LIGHT CACHE (Again if this is your secondary engine)
9. Once both MAPS are saved go back to the IRR MAP rollout and under the sub-title called MODE change the model spin box from SINGLE FRAME to FROM FILE. Below this spin box is FILE with a empty box next to it, navigate to where you saved the IRR MAP map and select it
10. Do step 9 again for the LIGHT CACHE
11. GLOBAL SWITCHES uncheck/un-tick DONT RENDER IMAGE
12. Set the OUTPUT to the final render size.
13. RENDER
Now your buffer should arrive as normal completely black, and rather then watch Vray calculate the illumination gradually, it will just start rendering the final image instantly
Work kindly provided by Tranganhhp (BTH) for object study
my attempt to render with other furniture; lights and materials
after that picture i change the floor and wall material (the latter only in the dimension of the material) and it can not render again, it gives me this error:
Failed to creat dump file: " ( error 183)
someone has an idea about what can be happening?? :-[ :-[
though not entirely of my authorship (but of “Master” Tranganhhp/BTH) my thanks in the same!..divided with him obviously! ;D ;D …unfortunately it walks half moved away of our community!
