actully the bump map kill the normal map and scene will be like a color map
note : test scene is a poly plane + directional light/aria light+chekcer/bulge as bump map

Hi
Procedural textures like checker and bulge aren't working with bump2d, that's a known issue.
bulge does work with aiBump2d
Thanks

if you pay attention to my post there are more parts. actually those are main parts
Procedural textures are just example
btw even with the aibump2d i couldnt achive bump with bulge here is my scene if u want to check
note : if my english isnt good enough to make my point let me know
tnx for help
i did 😉
i did not understand this part
(Convert your displacement to texture, then reapply as texture with tangent normal's as bump. This will give you better results than bump. good luck.)
what u mean buy convert displacement to texture? and the reaply with tangent normal as bump ? u mean normal map ? or i m missing something
right now im using a black and white map for bump or displace and its kinda working for displacement eithr
but there is some sort of issue when im trying to reapat uvs or the normal map and displacement map
there a shift between here is a example
in this case i repeat both normal map and displacement uvs for 3 time
left side is displacement map right side is normal map
even some times scale of displacement /normal map will change with my camera move in scene
Ok your problem was that you connected your bump incorrectly. the easy way to do this is to select your aistandard material, go down to the bump mapping tab, just underneath the reflection and refraction tab, click on the add node icon and select your arnold aibump2d Node. Then Select add node on the bumpmap options and choose your bulge. Increase the height and that should do the job.
thank you so mush now bump and depth working very well
i was folowing this guide https://support.solidangle.com/display/AFMUG/Bump2d i think they should change it. second bump node will make it work
now only a little problem left
as i said when im trying to use a displacement map in a very large scale scene like in the photo (in this case 5000 cm ) some messy will happen
displacement must be as same as it is in center of photo. but as you see its weird in sides
Looks to me like your displacement map Uv's aren't right upload your scene again, ill have a look. could be a number of things, but I think its a scale problem with your mapping.
its a simple plane i think itsnot uvs problem
must be something in scale or camera idk
im using centimeter system for scale
