we use Blender for Shapespark in the studio all the time without any difficulties.
What you have to be sure when it comes to texture mapping is that you do not introduce any edits to the textures in the shader editor - like changing tiling, texture rotation etc. You just have to UV map everything so it looks correctly in Blender and it should transfer fine into Shapespark.
@Danilo_Leite, it doesn’t matter what render engine you use in Blender. Shapespark has its own rendering system. It bakes lighting into textures and renders reflections and transparencies in realtime.
