Title: Cutaway shadow issue
Post by: djnoone on January 09, 2019, 12:56:53 am
On the screenshot the gray box is cutaway - inherit caps.
No hard lights are added, and even with no lights there is a hard shadow on the edge/groove cuted into the wood part.
The shadow is too intense on the edge.
In Cutaway - no caps the shadow is OK but i loose the texture inside the groove.
Is this a bug, or something is to be adjusted?

Hi,

When two objects are intersecting (in your example: the wooden block and the calendar card), there can be artifacts if you are applying a cutaway.
Unfortunately there is no fix other than actually modeling the groove.

Just to put some additional info for the subject - the bugs are interesting:

I also find strange stuff happening when using cutaways. Like cutaway object casting shadow onto nearest objects and similar.
Definitely a good start but you would be better off modelling the part as it should be.

if there is no any solution, take 2 shot which is one in full shadow mode (A),  and the another one will have any shadow in there (B).  then go to photoshop and put the 2 pics over and over and draw a nice, realistic shadow on the and then erase the rest of the pic B.
