hi,
great work thank you for the last build

love the eifel tower render!
I did some test with the "bump", or i'm doing something wrong, or i have really no idea.
I will definitely understand it better once you'll zip the sponza scene back.
so for now i did a test with MaxToLux v0.8.2501-beta, but with previous build i achieved the same.
for the test renders, i'm using the brick normal and bump png textures which are in the sponza pack together with Lux carpaint shader.
first pic: bump channel -> bump bitmap
second pic: bump channel -> lux normal -> normal bitmap ->scale 1
third pic: bump channel -> lux normal -> normal bitmap ->scale 0.002
forth pic: bump channel -> normal bitmap (no lux normal map)
sixth pic: normal channel -> normal bitmap
I see that when i use the normal blueish bitmap in the normal slot or the way you showed me "bump channel -> lux normal -> normal bitmap" the bump looks the same on the ball, looking the way it should i think smooth, but outwardly (inverted)
while the greyish bump bitmap in the bump channel looks very harsh, but inwardly, so does the normal bitmap in the norrmal channel while looking less harsh.
