Shadows = Low FPS

Hi there,

I'm busy with a funfair attraction simulation, and to make it look alittle bit better, I've decided to add shadows to it.

The model without shadows on 1024 x 768 = 110~ FPS
The model with shadows on 1024 x 768 = 34~ FPS

Each object has: my.shadow = on; - and in the main function I have: shadow_stencil = 3;

And this is how it looks:

Is there a way to avoid that big FPS loss?

Because this is really unacceptable!

Thanks in advance.

I would cast a shadow from a different LOD step, to increase the speed.

I've tried (also writen within the Main function)

shadow_lod = 0; and also tried 1/2/3, but no changes in FPS.

Does your model have LOD steps?

Looks like not..

Half the amount of polys in every mesh (using the mesh reducer), and use it as lod step 2.

Then you can set shadow_lod to 1.

Thanks alot, it got it fixed.

I will keep this in mind next time!

This is awesome^
