What is the limit of model size?

Is there anyway I can estimate the biggest size of model with texture that Shapespark can handle before creating models and start baking? If the tour is baked successfully, is there any possibility that the tour can’t be loaded or can’t run smoothly because it is too heavy.

If you know that your scene visitors will use a particular hardware, you can experiment with growing the scene size as long as the scene runs on the hardware. However, if you don’t know what devices the visitors will be using, which is the typical scenario, you have to adjust the scene size to an average desktop or mobile device. For such scenario, we recommend not to exceed 4M triangles in the scene and 2 lightmaps.
