I am watching some tutorials for substance designer and some of the artist use Tessellation in their view port and I wondered if this is bad practice or not? Doesn't tessellation of models slow down the rendering for game engines?
You can open any substance file in the Player, whether or not B2M is installed. It's just the default program in which any substance, B2M included, are opened.
Here is my latest personnal game character. Zbrush , substance designer , mari , substance painter. It was very fun . render using PBR in marmoset. www.vickz3D.com
My understanding is that unless you update the substance params at runtime, the substance is 'baked' into a texture and stored in a cache. So the final texture is calculated only once.
