Default 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.
