It ahouldn't be really negative review. Model is done well, but it has one big problem pf not having any possibility to controll self illumination of light itself. This defeats any purpose of this model. So, if you need light model that can cast any self illumination, stay just away from this. Or buy it, and modify it by spending hours of separating material polygons or making self illumination textures. Like said, model is great, but it has this big problem that all materials are baked. This is good for realtime graphics performance, but it shluld have atleast one more texture for self illumination mask. Petty, as it now, atleast for me, stays in "useless not production ready folder" instead in "great must to use". P. S. Support is fast but it couldn't solve problem explained above.
