Title: New User needs help / Normal Maps barely visible
Post by: Anthe.cr3 on 2021-11-08, 18:29:08

Hi there!

Long story short, been working with Blender for 3 years now, and just started out with Corona in Cinema4D, i noticed some issues concerning effect Normal maps have. They are barely visible (in my case)


I posted 3 Pictures, one is the (desired) result in Blender Cycles with the same Normal map, one picture with the result in Corona, and a third with the Corona Node Editor settings.
I tried to have similar lighting and angle for the screenshots


Troubleshooting:

-I have already checked if the Green needs to be inverted

-I Plugged the Bitmap to a Normal and this node then to the Bump channel

-I used Linear colorspace opposed to srgb or embedded Profile

-It's a DirectX Normal Map

-How can i adjust the Strength of the normal map in general?

-scaling of the model (Tire) is true to real world scale

I am sorry, if this is a repeated question, but i couldn't find any solution yet.

Thanks in advance!

What percentage is your bump strength set to in the main material node?

There is no Bump map plugged into the Normal Node, only the Normal Map Texture.

So changing the Strength under "Additional Bump Mapping" doesn't change anything for me.


See the Screenshot attached for more Info on my settings.


Thanks!!

Hello,

inside the Legacy material, in the Bump tab, there is also a "Strength" parameter. This is, by default, set to 10%. See if changing that helps.

Thanks,
Jan

Perhaps you can just share the file instead?

Hi

There is the File attached to this reply.

I added a Figure for scaling reference, and the Texture is 2k instead of 4k, to meet upload file size limits.


Any kind of help would be greatly appreciated.

PROBLEM SOLVED


Thanks Jan, i don't know why i haven't seen your reply.

Also i can't believe how blind i must have been, to not have seen, or not looked for the "bump strength" parameter inside the legacy Material "bump" part.



I was always looking at the "normal" node for further settings.


Apologizing for this trivial problem, hopefully this will at least help some other bloody beginner

I'm glad that you've got it right in the end.
