Will mesh size(scale) affect rendering result in PBR

Hey folks,

Just wondering will the mesh size in the scene affect rendering result in PBR in babylon? As far as I know in off-line rendering workflow (maya - arnold), the scale of mesh does matter. Size variants will lead to inaccurate calculation and slightly different rendering look.

For example, if we have 2 assets which are identical except that one is 100 times bigger than the other, and these 2 assets are using the same PBR material. In that case, will the rendering result look any different? (assuming camera positions will adjust accordingly, make sure both have same size in frame).

Many thanks,
Tawibox

As long as the size is not too big, it will not, it mostly comes down to the limitations of floating point value precision.
