    Do you have another method for converting hi-poly assets from Meshroom to low-poly, game-ready assets in Blender? If you do, I would love to hear from you.

    • @blenderbones

      Hmmm...perhaps the topic for a future video. I will think about that one :)

    I've tried following along with three or four other tutorials on this subject and was on the verge of rage-quit when I found yours. I finally got this to work! I don't know what I was missing from the others but this time success. Thank you!

    I see I'm not the only one for whom this video is the breakthrough for baking Normals. Excellent walkthrough of this procedure. I had two main problems, a conceptual one and a really basic one: target LowPoly mesh needs to have UVs unwrapped and a target image ready, and then, embarrassingly, I was trying to select the second target mesh with Shift+LMB not Ctrl+LMB... So that was never going to work.
    Your video covers steps fairly explicitly, at a no nonsense pace, and it is clearly labeled with large text throughout. Easy to follow and informative. Thank you so much for this outstanding tutorial.

    This is one of the most concise blender tutorials Ive seen. I always use the decimate modifier on high res model and call it a day, I'll be definitely trying this the next time i'm working on high poly mesh

    Tip to save time, just press stop in meshroom as it gets to the texturing process,
    Then you find your model in "Meshfiltering" then import that into your 3D app for cleanup and UV unwrapping.
    then bring back to meshroom for final texturing.
    Saves you ALOT of time.

    • @neilgordon1981

      You can right click any node in the tree and choose "compute" to only go as far as that node without having to monitor progress and press "stop" yourself.
      Regarding cleanup and bringing back to meshroom, I assume it'll work as long as you don't rotate or scale anything.
      How do you bring the model back in, though? Just save the same .obj format, remove mesh input noodle from the next node & paste the path to the updated mesh into the mesh attribute box of the next node?

      Cage baking is really helpul when your maps have glitches on the edges. To create a cage just duplicate your low poly and then select all faces and scale it among normals (it may look like a balloon). Here is a great video about it: ruclips.net/video/nJ0PM7m9TJc/видео.html

    Very nice tutorial but I'm having one issue. When I try to bake the diffuse texture, I get the error [No active image found in material "HiRes_Material" (0) for object "LowRes"]. I tried reselecting everything in the order you recommended but I couldn't get it to create any image files. Help on this step would be much appreciated.

    • @blenderbones
      @blenderbones  Год назад +1

      Hi. Many thanks for watching. Off the top of my head, I think the issue is that you haven't created an image node in your low-res model. You also need to ensure that that node is selected. I hope that helps.

    Hi blender bones. This is Santiago from Argentina. I am looking for the best way to decimate (and reduce file size) high resolution meshes of buildings. I really need to reduce file size considerably (10 x maybe?) without compromising photorealism and image resolution. Currently I am working on a mesh (obj file) which is 1.9 GB. Do you think the method you explain in these videos is the most suitable way to achieve what I am looking? Any other suggestion? Thank you so much

    • @blenderbones
      @blenderbones  3 года назад +1

      Hey, thanks for your comment. I suggest that this method is great for most models. However, if you are working with objects that have clean geometry, I would suggest using your high res models as a reference, and build using cubes, edge loops, extrudes, etc. In this way, you will have an accurate model with regards to proportion, whilst keeping the mesh size to a bare minimum. So, load up your high res model - go into wireframe view - drop a cube in there and start sizing it up to fit the original. Then delete/hide your hi-res model. You might need to go back and photograph the original building, to get better textures for each side of your model. I hope this helps. I have only explained a fraction of what you need to do here, but hopefully it will lead you onto the right path.

    Do you have a video of how to fill holes (I've captures some 3D objects only from the front, I need to fill in the back)

    • @blenderbones
      @blenderbones  2 года назад +1

      Hi. To fill holes:
      1.Tab into edit mode in Blender.
      2.Select vertex or edge select.
      3.Select the edges or vertexes around the hole.
      4.Press 'F' on the keyboard to fill.
      5.Use the knife tool 'K' to cut up the fill into four sided faces.
      6.Re-texture using the Clone tool in the Texturing Paint tab.
      There are other methods, but this is the easiest to explain.. I hope it goes well.

    The important thing is most of the time the Instant mesh is having lot of open spaces between the mesh faces.. its hard to solve. DO you have any suggestion In getting clean remesh

    • @blenderbones
      @blenderbones  Год назад

      Sorry for the delay in getting back to this. I suggest you remodel it as best you can and then, with the optimised mesh imported, fix it up in Blender. If it is a matter of just getting a better mesh, I suggest taking a look at the comb tool within Instant mesh. Spend a bit of time, combing in the direction you want the mesh to run in. I hope I have answered your question.
