Thank you for your submission to the Unity Asset Store.
We’ve reviewed the submission and consistent with the criteria considered in our approval process, we have chosen not to publish this asset. However, we greatly appreciate the time and effort spent in preparing your submission.
To be blunt it’s a simple chair. Looks like you just assigned a brown color to it and it isn’t textured.
To put something like that in the store, you need to step it up several degrees and include more then a simple chair.
It has to be better quality.
You’d want to do something like this:
Obviously, if you look at the items in the asset store, it does not have to look like the items above.
However, the chair has no texture so unusable. Also, it is very simple. It is good to start on simple things but you need to learn to texture. I know so many people who tell me, “I can build models, but can’t texture.” You CAN texture, you just have to spend the time learning to do it. No one wants to texture your models.
Matter of fact, if the object wasn’t UV unwrapped, I wouldn’t even know HOW to texture it!
Definitely agree with the others here, though. As Teila said, it doesn’t have to be AAA quality, but it should be something useful and of a reasonable quality. Yes, there are some crap assets that have slipped through and remain available for download or (worse) sale. But yours got caught!
Expand your asset to include other similar items. Maybe like 20 kinds of chairs. Or tables, benches, trash barrels, etc. Hunt through the asset store and find stuff that doesn’t exist yet. Create that, bundle it all together, and release it as a pack. That holds more value to customers and may help your chances of getting approved.
Lastly, carefully review the asset store guidelines, and be sure your asset meets all the requirements. Don’t give up! Improve your work, then try again!
A simple chair is one thing. But if it doesn’t have a UV map, that is unacceptable. 3D models with no UV map can’t effectively be used in mobile applications, and wouldn’t be efficient to use for desktop applications. There are certain minimum standards that have to be met.
Oddly enough, the OP’s other 2 posts were the following threads:
The first post mentions being rejected, and I assume if he knew about the .tga requirement, he would have already known why the asset was rejected…
I think we may have a “refuses to learn” situation on our hands.
Ok now don’t be too rough on em haha.
I’ll admit that the chair, it is super basic. I could create that in blender, maya, or 3ds max in like, ten minutes - and I’m not an artist lol. If I was determined, in maya or blender (not sure how in max) I could unwrap and texture it to look like wood or something. And for real I suck at it, but I took a 3d modelling class and knew afterwards I better stick to code haha.
I’m not saying you can’t do this, anybody can if your willing to learn and apply yourself to it. Develop a passion for it, make things your proud to submit to the asset store!
What you need to do is create more organic stuff, try adding curves to it, yet keeping it low poly, and make it your own, detail some little tiny areas like rounded bars across the back, legs that are rounded squares. And definitely learn to unwrap and texture in your 3d modelling program. It’s a must, no retail games use untextured models unless it’s got some special artsy look where everything is flat colored. Plus leaving it without a texture screws a bunch of people from using it, because they don’t even model or know how (or what is) to unwrap and texture a model.
So spend like a week on it. A whole week on that one chair. Watch YouTube videos of pro artists doing amazing things and literally copy their work flow step by step. See how they unwrap (find vids using your modelling program) and texture, then do it. If you can’t do it once, keep trying. Start from scratch. Do it until your sick of it and just want to quit. Then keep trying.
How’s that saying go? “Build it and they will come”.
Edit: Oh came up with another one. "Never give up. Trust your instincts. "
I know why you were rejected. The reason is mentioned in this video.
Awww snap busting out the Rick rolls
I didn’t know people even still did that anymore… 
Rick no…
