Re: Help creating new object & light source from scratch Again, knowledge you would have gained when you had started of a slower instead of diving directly into advanced topics laughing There's another manual on dodecagon.nl that explains changing material names. Reading that manual will make it more clear what happens when you change material names and the relation between "usemtl" in the obj file and "newmtl" in the mtl file. Yeah, I understand I was too ambitious and impatient. I was being honest when I said that I'd read those files before. At 1st pass, they didn't make sense to me at all, and yes, I was trying to work through the exercises as well, but the downloaded files appeared as if the exercises had already been done. The files had already been altered correctly.). At 2nd, I started to understand, but I got stressed. That never helps me learn. Going back over them a 3rd and 4th time, they do make more sense to me now, but I still don't fully get them. As much as I appreciate the manuals being brief and to the point, lacking a broader understanding has caused me problems. I'd been experimenting, limiting the adjustments to making the object into a light, but that hadn't worked at the time. That said, it looks like I’ve finally done it correctly. The lamp on the far right, I just grabbed from the library so I had something to compare my Brace lights to. Everything else are my brace lights at 1%. I’d set them that low before and they weren’t showing up but it must have been something else. Also the picture taking app in SH3D choked trying to take this picture. I finally had to leave it go for a while and came back to found it had finally finished. https://www.dropbox.com/scl/fi/ppa8d3sh7z5hpi...&st=lydlg0y6&dl=0 There were a number of places that I suspect were contributing to the problems I was having. I think maybe a significant part of my problems stemmed from how I was organizing my files. I don’t understand how the files work together. When I bring an item into Furniture Library Editor, is the program only drawing on the data stored in the SH3F file? If I have the brace open in the FLE, should I then delete the existing obj. & mtl. Files for that very object, or does the FLE modify those automatically? When I would bring an object into a project in SH3D or the FLE, I thought that they were still drawing data from the obj, & mtl, files of the object So I wasn’t deleting them. I thought I had misunderstood instructions. I think I understand how the obj. and mtl. Files work with each other, and that I have to use the same object name between them, but can the file name be something different? Can I use ‘Structural Brace with Light’ as the file name, and eventually what it’ll be listed as in SH3D, if I use ‘light’ and ‘brace’ for the internal file purposes within those files? I started deleting older files as I went a while back to try to narrow down the problems. I decided to run a full search in 2 of my drives about an hour ago and found at least two additional locations I had started storing files (including libraries) that I’d forgotten about. I think this was also why I was having so much trouble deleting files with the Furniture Library Editor. Make sure you have the level elevations as mentioned in my previous post. I went to check this. At one point I did have the level elevations you suggested, but I may have started a new file and lost it at some point. I checked this round and made sure to set up the Levels correctly again, as you mentioned. Check the obj and mtl files and change the material name to "Brace" if you hadn't done that yet. Something else I don't understand even after reading those manuals. I named the FILE:'Structural Brace' In the obj. file for it one of the top lines says, 'mtllib Structural_Brace.mtl' This is just a tag to find it in the library, isn’t it? I cut and paste the file name into the obj. text when needed. I don't know if my not using any underscores was causing a problem? Anyway, it’s done. I did it. Correctly. Finally. Thank you again for your help with this. That said, I now have some more questions where I didn’t find the answers in the manuals, but I need to take a beat. This was kind of exhausting. |
