take a look, will this version work in the mod? This is a simplified geometry; I baked the normal map from the high-poly throne onto this one, and then I made it gray in Photoshop, like stone... It's clear that the chair itself is essentially smooth; all the bricks on it are just drawn. I did go over it a bit with a brush to highlight some of the protrusions that should be in the place of the bricks, but the simplified geometry doesn't allow me to clearly define each brick.
P.S. I think it might be possible to do a retopology, placing polygons strictly along the bricks, following their shape, and making the gaps a depression, but this is a very time-consuming task, and I'm not sure how many polygons it will require. Of course, it will be fewer than in the high-poly version, but I'm not sure if it will be significantly fewer, as there are a lot of stones...
I think we need to approach this throne in a smarter way.
We could use a natural, lava-style throne instead of a man-made one – as if a gnome wizard struck it with his staff, and different stones emerged from the ground, forming the throne.
We could use models of stones from the lava lands as a base; we wouldn't even need to paint them.
These magma rectangles and spikes appeal to me with their simple, natural angularity.
This is probably another case of professional deformation, haha. I often decorate units with the models I have, so I'm assembling the throne from models
