Re: Photogrammetry Textures
@ okorynal, What do you find hard in the photogrammetry workflow? At this point it feels pretty straightforward to me. The only thing I'd improve would be to have a plugin to reproduce every step of the tiling in Photoshop both on the diffuse and heightmap. I do not believe automatic tiling software will be good enough… -
Re: Photogrammetry Textures
Hi Okorynal Tiling is by far the most difficult bit of all. I'll try to explain as precisely as I can though. So after you baked the scan on a low poly plane you get a very big texture such as this Select an area that will be your base, as a rule of thumb I try to select the biggest square I can draw Copy both the selected… -
Re: Photogrammetry Textures
Fixing the seam is actually not that complicated. I proceed as follows : * Usually when I'm done processing my texture in Agisoft, I don't have an area with a perfect square that I can just bake. To get around this I just draw a low-poly surface (usually in 3D Coat) This surface doesn't have to be a square at alll, it's… -
Re: Photogrammetry Textures
Are you asking about the best way to bake the diffuse map? I've actually run into problems there in the past. Seems the standard way is to import your lowpoly mesh into photoscan and build the textures there, but sometimes if your lowpoly is not similar enough to the hipoly, the newly built textures come out bad and… -
Re: Photogrammetry Textures
Thanks ! :) I'm indeed using the record action, however not with the clone stamp. I export both the diffuse and height. Then I tile both of them at the same time (with record action) and displace the height again to bake all other maps. The reason I'm not using the clone stamp is because it may create differences between… -
Re: Photogrammetry Textures
This is a very good idea, I'll try it for my next texture, thanks ! The only downside of this is that you have to assume everything will be fine while working on one of the two textures, and then apply everything on the second one. Even though I focus more on the diffuse during the tiling process, I like to toggle the… -
Re: Photogrammetry Textures
Nice scans. Are you using the record action (clone stamp) method for tiling your multi-image maps? Also, what maps do you export? Diffuse+normal+height? -
Re: Photogrammetry Textures
I never had that issue. However I found it safer to record and replay each action after the other rather than doing everything on the diffuse and replay everything on the height. Maybe doing so will avoid your issue -
Re: Photogrammetry Textures
Hmm, when i play recorded actions they seem to mess up. Is there a trick to having the playback ignore mismatching layers? IE i have "group diffuse" and "group height", with differently named layers in them, aka "diffuselayer" and "heightlayer". My playback records operations on "diffuselayer", and it can't find a… -
Re: Photogrammetry Textures
I know that's kind of an old post. I'm just curious if you've ever just recorded your strokes within photoshop and pasted that on another layer, reduces the need for masks almost entirely. I tried the method you described in your pdf a while ago and found just recording strokes using a spot heal brush on my diffuse layer…
