Installing the latest update (3.30.05), I have “Normal Bump is Not Compatible With Vray” Error Message being displayed during rendering.
Many of my older assets use this map. (because there was no additional bump slot in VrayNormal map in the earlier versions)
Isn’t Normal Bump anymore supported in Vray? Do VrayNormalMap give better results than Normal Bump?
It is supported on regular meshes, but the “Normal Map” texture crashes on V-Ray proxies and other V-Ray specific geometry and we can’t fix this on our end. We had so many support issues related to this that we decided to print out this warning and guide users to the VRayNormalMap texture instead. We will also update the V-Ray scene converter to do this conversion.
Best regards,
Vlado
Hello 
I’ve found this piece of code a few days ago, not sure it can help (not tested yet):
try(destroydialog ::vrnRoll) catch()
rollout vrnRoll “NormalMap Convertor” width:168 height:30
(
button btn “NormalMap to VrayNormalMap”
fn getMaterial arr = for i in arr where isKindOf i VRayMtl collect i
on btn pressed do
(
for g in geometry where g.mat != undefined and (ins = getClassInstances Normal_Bump target:g.mat).count != 0 do
(
for m in ins where (isKindOf m.Normal_map Bitmaptex) do
(
NMap = VRayNormalMap name:(m.name) normal_map:(m.Normal_map)
if (arr = getMaterial (refs.dependents m.Normal_map)).count > 0 do (for n in arr do n.texmap_bump = NMap)
)
)
)
)
createDialog vrnRoll style:#(#style_titlebar, #style_sysmenu, #style_toolwindow)
I perfectly understand. So it is time to convert these maps to VrayNormal. Thanks for the clarification.
Many thanks
Thanks to Pixela and Vlado I have this problem too, more on trees which I’ve created with SpeedTree!
and I have a question from both of you guys and I’ll be so pleased if you give me an answer, The answer is which normal map creator program does work better with V-ray?
Thanks in advanced
I have been posting about this for a couple months. They happen on every project and the error will repeat thousands of times.
It didnt work on my scene.
You know, it doesn’t work for all the normal errors but does for most.
I couldnt run the script, it gives error.
This worked for me
Thank you
Some of the errors can be fixed my converting the bump map to a V-Ray Normal Map.
