Tesselation Map vs Height Map

[Killer.Penguin]

I'm trying to understand Tesselation in Unigine.

 

I notice there's two testure slot, namely: Tesselation Map and Height Map. So what's the different between the two? Is Tesselation Map tell the engine where it should split more polys? Should it be black and white?

Hi,

 

I think you can find difference in this table: https://developer.unigine.com/en/docs/1.0/content/materials/mesh_tessellation_base/#textures

In addition, you can check article on how to create tessellation material here: https://developer.unigine.com/en/docs/1.0/tutorials/tessellation/

Oh cool, I didn't notice the whole material section in your doc.

 

Anyway, we're trying to export them directly from zbrush... height maps should be the same right?

you might want to experiment with the offset.
i usually bake displacements with turtle - using offset of 0.25 - and then gamma correction of 2,2
if scene in maya is baked in centimeters (not sure if important), in unigine render parameters i use a global scale of 0.01 - then i can set scale within shader to 1
power to 0.1
this gives good result ensuring vertices that "touch" the highpoly source-mesh will stay in place, what sticks out - is being displaced outwards, and what goes in inwards accordingly.

i was not succesful adjusting this "offset" with photoshop - not sure what the offset value in maya-2dTexture nodes would be if translated to photoshop, nor i have tried directly from zbrush, yet.
but if your results seem to be a bit "off" - those things should be kept in mind.

but i haven't tried with 8bit yet ^^ will give an update regarding that soon :), since soon i exceed memory limits of titan,..
