Blender OBJ in stardust : all I get is plain colors
Hi,
I am testing Stardust … and that’s great. But the documentation is not as explicit as it could be …
I imported an OBJ from Blender. It has 2 materials and the 2 colors appear, but only with an ambient light, and there’s no shadow or reflection.
I just get plain colors.
If I switch it to a point light or spot light, the OBJ is black.
I have been struggling with the options for a few hours and it seems I have tried every possible option in Stardust.
Any clue ?
Thanks,

If I recall right, it has something to do with the UV mapping selection. Try switching the mapping from the default. Haven’t used Stardust that much yet, but I ran into the same issue and I think it was either changing the mapping or the material that fixed it.

Hi Kalleheikki !
Thank you (once again). Yes, it is the UV mapping. I changed UV Mapping Model to Sphere … Isn’t it weird ? Sphere ?! ????
For my model is not a sphere but … an OBJ model. I think that, without your help, it would have taken another week for me to find this …
Before :
After :
It is not perfect yet but … there is probably some quality parameter somewhere that I am going to find …
Great !

… I forgot :
Did you deal with this issue while importing an OBJ from Blender ? … I think you told me you don’t use Blender that much.
So it’s not a Blender to Stardust problem … rather reassuring for I dread that king of ultra-specific oddities that kill your day …

I use Blender plenty, but I haven’t used the combination of Blender export to Stardust import more than a couple of times. I would expect it to work if the model was exported with UVs from Blender.

Well, I am going to re-learn Blender. 5 years or more is enough to forget most of what I knew. I will try the export with UV.
The low quality issue a got (2nd image) was solved when I removed the motion blur option of Stardust.

On the plus side, Stardust customer support is very responsive. Talked to them plenty this past week. There’s light at the end of the tunnel: They are working on node-specific sample files that (as I understood it) are going to be linked to directly from the manual. So (hopefully soon) it should be easier to learn what the logic behind each node is.

Great !

Did you use the forum or did you send an email to them directly ? ( I tried the forum a couple of days ago and my post is not published yet … ans some are 8 months old or more and did not get any answer).

After 2 days of work in Blender, I believe that importing OBJ’s to AE to use them in Stardust is not as simple as … working with Blender.
In fact, the last time I used it professionally, it was 10 years ago, and seeing what it became generates a lot of enthusiasm in this room …It has everything, and everything is in total control with scripting. For instance, if I want to draw the trajectory of a particle, it’s … easy here, and impossible in Stardust. And, if you have a question … type it in Google … and Bam ! … a page full of answers … It’s not a community, it’s a country.
Well, let’s compare the next image I created in blender with the ones above in this thread :
That said, AE is still the way to go for a lot of things …
I am probably not going to buy Stardust or Trapcode now. Coding vs [ setting a finite number of options ]. Not such a simple choice but for the moment I choose code.
… but I may change my mind next week … 😀

I know what you mean. Blender is so powerful today, it makes me question the need for any commercial 3D programs — although I am still considering C4D.
I haven’t been able to use Stardust for any production purpose as yet. Feels like the program is in some sort of public beta stage. E-mail support is very fast, but that alone doesn’t resolve the need for better documentation. I guess I’ll return to it when the user guide is up to snuff.
