This is a question I was asking myself during last times I used gamestudio: using blocks or model entities for static models on our levels.

I found that using blocks (adding models via WED's import from MDL) gives a better performance as it takes advantage of gamestudio's BSP/ABT and they can make use of lightmaps. However it has some disadvantages: all textures are stored in a WAD file so handlig them is less user-friendly. Also some shaders do not work well with blocks.

On the other side, when using models as entities it is easier to make changes in the original models as you don't have to import them again, texture handling is easier and shaders work fine. However, you don't have GS calculated lightmaps.

What do you think about this? are you using blocks or models for static objects on your projects?
