Keyshot 5 Rendering Issues

[timdiaz3d]

So for whatever reason whenever I bring any object from 3Ds Max or Maya into Keyshot 5 I get extremely weird results

Is there any reason why this is happening now?
I am using Max and Maya 2014
my computer specs are:
AMD FX-8150 Eight Core Processor
32.0GB Ram
Nvidia GeForce GTX 680

Keyshot Version is 5.099

Are you using calculate normals on import ?

The images you are showing look as if the face normals are not unified. Are importing OBJ or FBX ?

I have tried calculating both on and off and each outcome is the same. So what I have tried
I started in 3ds max,  collapsed all modifiers on every mesh, reset the xform, then add another edit poly modifier to unify any changed normals then collapsed again.
After that I run an STL Check modifier to make sure my verts are welded and any other issues that might be there. I got a few errors that said I had open holes but they are in areas that will be under the ground so it's not an issues and never was in keyshot. Anyway I export the scene to a obj with maya presets.

That has been my usual set up before going into keyshot And has always worked until the update to 5.099

So when that issue I mentioned came up I went back into max and re-exported as an FBX while doing all that I wrote earlier in this reply. Same result.

So I went to am earlier version of the file and instead of collapsing I just exported it flat out as an obj. Same thing happened. So I tried FBX. Same thing. So then I tried the Max to keyshot plug in, that made it even worse. So then I tried a .3ds file. That failed as well.

So after that I copied the file, went to my older machine and saved it out on max 2012 and exported it out as an obj and FBX. Brought it into keyshot 5, still failed.

So then I figured maybe I need to reinstall my software but before I go through that mess I decided to test the obj that was failing in maya 2014, it came in fine with no issues. I tried the same obj on my wife's machine and loaded it in maya 2015 with no issues and then in XSI 2015 with no issues and then in MODO 701 with no issues.

So then I tried saving the file under the new packages and then exporting out of every 3d package my wife and I have and sadly I still got the same results even after using each programs normal pipeline, transform freezer, history eraser and so on and so on and after about 6 hours of back and forth it all failed.

I did however find a couple threads that have this exact issue in the keyshot forums and it seems to probably be an issue with the current version where it gets wonky if you have an AMD processor which I do have. The answers those artists received was that there is a fix in 5.1 but no one is sure when that will be released. So hopefully that fix is the answer to my problem because when I got keyshot 5.01 I had no issues at all and it was only after moving to 5.099 where the trouble started.

Wow Tim, I think I would be ready to kill after all that messing about. Just out of pure curiosity what happens if you set KS to use 1 core before you import, maybe it will sort itself out with just one core working on the file, it it comes in good, try going up the cores and see if it gets back unto full speed with no issues

I tried the using less cores. Still the same issues. Hopefully a fix for the issue will come soon. I do freelance work on the side and Keyshot is one of the things I need for the jobs I get, so this is a big issue for me.

However I just tried my exact file in Keyshot 4 and it has no issues. So I'm 99% sure this is that AMD issue that has been reported already. Anyway if there might be able to get on the beta for Keyshot 5.1 would appreciated. I can work using Keyshot 4 but a lot of the features that Keyshot 5 is known for I use all the time and it is a lot harder in Keyshot 4

Hello. I imported my model from SolidWorks 2014 and the same problem is happening. KS is showing mesh model. I did the import using the menu and also the plug-in. I also tried to reduce or increase the mesh using the Tessellation Quality feature. Not resolved. 

My Specs:
- Processor: AMD FX-6100
- MEM: 24GB
- Motherboard: Asus M5A99X EVO R2.0
- NVidia GTX 550Ti
- OS: Windows 7
- KS Version: 5.0.99

I ran into a similar problem, as I found out it was due to the fact that I downloaded the model through File - Import, then I opened the model through the File - Open, and it all fell to work.

I find with many instances of using exported models that deleting the vertex normal map before importing it in to anything else is a pretty likely fix for these kind of issues. I don't use solidworks so it might be something different, but might be worth looking at. At work if the CAD guy gives me an OBJ (actually, they are from solidworks!) when bringing in to Lightwave the models always look faceted and with random shading on polygons. As soon as I delete the vertex normal map, the models look properly shaded.

Cheers!

Same issue here...
Using SolidWorks 2013, with Keyshot 5.099 + Kshot plugin. No exporting. SolidWorks quality set to max.

On the second image, can see the same piece rendered under Keyshot 4.3.

My Specs
AMD FX8320 @ 3.5Ghz

So does this mean to say that there is no fix for this issue yet? Cause I'm having the same problems with automotive renders
