Stealing Reality - Photoscanning with KIRI Engine and Blender

Check out my new procedural modelling bundle: www.nodegroup.xyz/procedural-...
Photoscanning is an extremely undervalued skill for 3D artists - especially now that it's so easy. In this session we'll be walking through using Kiri Engine to create a scan and process it with Blender 4.0.

That was excellent and revealed a few new details about Blender for me. Thank you very much for everything you do.

Very cool demo Erin. I love photogrammetry and like to keep up to date and hadn't heard of KIRI engine. Thanks for the demo. I love using a turntable and scanning on a black surface. I have used a few different programs in the past and I really like Substance 3D sampler (PC app) and Qlone (iOS app) as well. I just downloaded KIRI engine as well to play with it.

Thanks! The featureless ai scan is another plus of Kiri if you want to scan plainer objects without covering them in tracks

1:52 I knew you'd shoehorn geometry nodes in there somehow.

what got me into blender from Maya, only because of geometry nodes I was able to get myself to finally learn blender and start doing 3D again @@Erindale

If you are on windows and have a GPU, meshroom is free and works well.

@Erindale 8 ай бұрын

That’s what I used to use and it is good but I don’t see it as very viable for beginners with all the extra options and customisation. Great once you understand it but Kiri gives very good results with essentially no knowledge requirement

very good dear Erin! do you have any experiences with meshroom? it's open source and easy I believe. I have it but never done photogrammetry with it. since you did with Kiri, it would be a nice comparison if you had experience with meshroom as well.

@Erindale 8 ай бұрын

I used to use mushroom a lot. It has good defaults and it’s quite configurable. You still need to sort your own photos and lots of other manual steps so for me, it’s not worth it when apps like Kiri engine and reality capture etc can do as good or better completely automated on your phone that you have with you. Being able to process and check a scan worked properly before you drive home is often very helpful

Thanks for this great video! i am able to follow till baking- i have a camera as object and after remeshing and uv unwrapping, the diffuse color is all over the model (i have only one object and followed baking step by step...). any suggestions? am i missing something?

@Erindale 6 ай бұрын

So you remesh and unwrapped and then the diffuse colour is on the model in the wrong places? That would suggest that you need to bake the diffuse from the original onto your remeshed version (using a new image texture to bake onto). You should have two objects, one being the original scan and one being the retopologised version you want to bake the textures onto

@hanon3317 6 ай бұрын

Thanks again Erin! I played now some days around...- Turned out, that if I enter a value (0,1) into extrusion ( in the "selected to active" menue ) baking works as intended.

@pile333 8 ай бұрын

Is retopo always needed to 3D print photogrammetry objects?

@Erindale 8 ай бұрын

Not always but I’d recommend at least doing the steps I did here to create a manifold topology with no random floating islands or thin geometry that a printer won’t manage to reproduce

@toriigatedigital 7 ай бұрын

Have you played around with Gaussian splatting?

@Erindale 7 ай бұрын

I have, it’s very promising. I’m looking forward to when we have text to splat AI and a robust method for animating splats. At that point it would be reasonable to think we can create entire experiences without any need for 3D modelling 🙌

@siberstormgd4957 8 ай бұрын

When i Remesh the mesh kinda dissapears into little dots any help?

@Erindale 8 ай бұрын

This probably means that your mesh is not watertight. This is why I made sure that my booleans create that closed face on the underside

Bro.... 360k tris - that's too much...

@Erindale 8 ай бұрын

Too much for real time rendering but a lot of industries won’t care about mesh density. I’ve used plenty of raw photoscans back when I was doing archvis

@Erindale ...and won't care about UVs 😅.
