Simple 3dsmax Checker map, with two striped gradients in slots.
When I apply it to Diffuse, it looks okay:
But when I drag it into the Bump slot, then here’s what happens:
On one checker - two gradients get mixed, and the other checker looks like it’s empty.
Same happens to noise+gradient in checker slots, two bitmaps in checker slots, etc…

Good old blur bug?
Can I put my bump values above 1? or it can lead to artifacts? Sometimes the value of 1 is very small.
forgive me for my English translator.
yes, the artifacts arise from a combination of factor, not this single one. You can also set max normal difference in general render settings to higher number, because it acts as a upper limit of how much is bump allowed to change a normal.
What does blur has to do with that?
Here’s the scene for test: https://dl.dropbox.com/u/9944031/checkerTest.max
Here’s the Checker map in the Diffuse slot:
And here’s the same Checker map put in the Bump slot:
I guess it’s obvious that half of the squares just dissapeared, and the other ones have two textures rendered mixed (Cellular+Gradient).
