About scene Dinning-room #2

Hi!
Thanks for your amazing job! Could you please tell me how you convert the dining-room.blend file to many separate obj files? I use blender to read dining-room.blend and then export to obj, but I could only get one big obj file. Thanks for your help!

Hi, You can use the split mesh by material feature in Blender. Select an object -> Edit Mode -> Press P -> By Material. Then select the mesh and export only the selected object as an obj file. It takes a while to do it for big scenes since its a manual process. The dining scene took me about an hour or so to specify all the materials (Since I'm using only the Disney BRDF) and export the meshes.

Hi! Thanks for sharing your work, really nice!

Unfortunately I"m not professional with Blender, would you be so kind to upload the obj files for the DiningRoom/Bedroom scene?

Thanks for your time.

knightcrawler25 commented 6 years ago

Sure :) I'll upload the files for both the scenes when I get back from work. The bedroom scene is from https://benedikt-bitterli.me/resources/ You'll find lots of interesting scenes on that site as well

I've added all the .obj files with the latest commit into the src/data/data.rar file. Unzip the file in the same folder and you'll be able to run all the scene files :)

Amazing work! I have a question about the way to generate scene files. How did you get scene files as such a format? If I want to render other scenes, how can I generate such a x.scene file? Thank you!

knightcrawler25 commented 5 years ago

@qzzone It's mostly manual generation. copy + paste and modify as required. I didn't focus much on scene file generation/loading as I wanted the code to work first before improving anything else.
