Floor drawing problem

I have a building with about 10 floors. Each floor is its own png picture in the model (the pictures are located one on top of another) . The pictures are all the same size - they are quite big with lot of empty space around the buildings (as there are several buildings in the model). The empty area is transparent and the buildings have some colour. The problem is that sometimes the corner of the picture is drawn in a strange way. So when the model is rotated, the corner is can be seen (there is nothing really in the corner)

Can this be fixed somehow easily?

Hi @Tomi Kosunen,

It's hard to know how to help without looking at your model. To receive a more accurate solution, please post your model or a sample model that demonstrates your question.

@Ryan Clark Here's an example. This is not a big issue but if there is an easy fix, it would be nice.

If you rotate and zoom the model, you'll see the white corner in the horizon.

This is a bug with the view fog calculation. The view fog setting makes objects blend into the background color as they get further away from the camera.

The simplest solution right now is to turn off the view fog by setting it to 0:

I'll add a case to the dev list to fix the view fog shader code so that it isn't incorrectly blending the alpha value.

You might also want to re-rank your objects in the tree so that the transparent objects are drawn back-to-front. You can make the transparent objects draw last by moving them to the top of the tree. The object you want drawn on top should be at the top of the tree. So, for example, you should put the FlexsimModelFloor object below the Plane objects so that they are drawn on top of it.
