Does Shapespark limit square of model when baking lighting?
i had a inform that i could not bake lighting bacause model is too large.
The error message should contain a suggested lightmap resolution that will work for the model, is this the case? If yes, you can either change the Lightmap resolution setting of the whole model (the editor Bake tab), or change it only for the objects with largest area, for example terrain (the editor Objects tab).
Your mean that i should reduce lightmap resplution?
Yes, this should help.
