shadows
 

Hi,
Is there a general rule that the bigger your model, the higher the depth map resolution needs to be.

I have a massive model of an aircraft carrier and the Dmap is over 3ooo, and the shadows are still naf. I can go down to 512 if I scale the model down to about the size of my grid.

So bigger the model, higher the Dmap?

cheers

pretty much. Dmap shadows are literally a big image that is spread over your scene for the shadows.

3000 isnt THAT big. What's the largest map you can have? use that! :) try playing with the filter size aswell that should improve your shadows a bit :)

3000, whaaaaat!?! Generally you want to keep dmap resolution as low as possible. It's a balance between mainly resolution and filter size. The goal of course is to get descent shadows as quickly as possible.

I got many lights on my Andrea Gail project. Currently I'm adding lights inside the cockpit. I've found out that a resolution of 64 and filter size of 2 is enough for these lights (frame resolution is 720x432)...

But my frame rez is 3000 px, as im rendering out for print.
The shadows only improve the higher I have the Dmap. But I cant go any higher then 4000 as the computer cant handle it.

have you played enough with Dmap silter size?

if that still doesnt gets you good shadows use raytracing...
