Hello, seeking troubleshooting assistance with another school model. The issue is again upon exporting to another software - Poser and DAZ 3D Studio in this case, prior problems in KeyShot and Maya - the render has serious errors.
It appears, for lack of a better description, there is a “break” somewhere in the geometry and it “bleeds” out to create stray polygons that look like streamers created with incorrectly facing Normals. This is not the case, however, as I use a specific Blue/Yellow high-contrast scheme to reveal any errors with misplaced Normals. I have had the same problem with models built exclusively in Maya as well, suggesting it is a geometry problem versus being exclusive to software.
Originally, the models were exported in default colors, and the “streamer” problem persisted. Then all parts were colored in SketchUp to clearly establish Material Zones, yet the problem persists.
Robot Arm Section. All conspicuous features, such as curves and chamfers, are made from Quads. No Tris are used anywhere in my models. The large flat areas of course, create N-Gons. Note the high-contrast yellow, showing a hole in the cylinder socket that was sealed before OBJ export.
Geometry visible:
Note the high-contrast yellow. I do not believe the issue is with incorrectly facing Normals.
After sealing all holes during construction and double-checking all Normals are facing correctly, the test renders my friend did showed this. The dark areas along the sides are stray “bleeds” in the render that hide the chamfered insets:
Serious issues where the OBJ Export does not correctly recreate all Edge Lines. They are there, but not recognized by the software upon rendering. Note the voids in the contour lines of the Chamfered Inset:
No idea why it fails to see all of the chamfered inset:
Note Chamfer Inset geometry:
Inset is lost, despite the part being present. My colleague believes it is due to a registry line I used for construction needs, visible as the heavy “shadow” in the render
Next step, I eliminated all chamfer insets to simplify the model, yet there were still issues with the render. Defined creases “melted”. I would guess from lack of Edge Loops as with Maya? Also more creases and “streamers” that should not be there.
I need help, please, in understanding what this problem is. I do not know what to call it, making searching for information difficult. I REALLY NEED to solve this rendering problem, as I am trying to build props for my friend’s 3D Comics, but also trying start up a garage business of 3D models for Poser and DAZ 3D Studio.
This problem has held me back more than two years now. I have no illusions over the job market in the game or movie industry, I will be graduating college soon; so I must do something to build a real world portfolio of marketable items to “get my foot in the door”. There are artists who make their living with their 3D model business on sites like TurboSquid, CG Trader, DAZ, Renderosity and others. I may actually need to resort to that . . .
As my resume gets deleted the moment the software filters read “United States Army Veteran”. Discrimination that can be explained away as the perils of a “Buyer’s Market” for employers. I doubt any human eyes have ever read of my experience and qualifications or I would not be getting increasingly desperate about future employment.
Thank you for your time.
