Hello,
I worked recently with RC quite a lot and I’d like to ask you about the issues I came across during my work:
-
5 from 15 my projects weren’t saved correctly (screenshot attached). I went through all steps, so at the end I had a textured model, (I was saving project after each step) but when I open it next day I had only 2 aligned cameras, nothing more. It always looked as screenshot shows. Please, don’t tell me it’s related with the cache and actually there is no working save.
-
“Start” button. What it supposed to do? I understood that at the end I should get a textured model, but actually model wasn’t unwrapped neither textured. So I had to go back a few steps…
-
Actually I had to go back to a “simplify” step which leads me to this 3rd issue: why “simplify” is excluded from the “start” button? Even in case it would work, at the end I would get ~100mln poly mesh which is not usable in my case. I would have to destroy 50% of work, go back and simplify, unwrap and texture it. Am I missing something or the process isn’t perfect?
4)With this one I’m not sure, because once I got a good results and in other project not really.
Does “texture” button does an unwrap as well? This is logic right? The problem is that after I used that option, I mean after:
align>create mesh>texture>export I wasn’t able to export a texture. I had to go back, hit an unwrap and then texture.
I use cannon 5d, 35mm lens, have about 200-500 photos per project.
It would be great if you could clarify/ mark as bugs/ improve/ comment those issues. Other than that RS is great 
Feature request: delighting. I’m not sure how, but It would be great to remove light and shadows from my meshes. Maybe with a hdr panorama, or chrome ball?
Thanks,
kurt
When you open an existing project RC shows you the first component.
That is not necessarily the one you had reconstructed.
You need to set one of the views to “1D” and select the component with the most aligned cameras as that is what you likely got reconstructed.
The Start button is basically a one-stop thing that will do a basic reconstruction.
I would advise you do the steps manually.
Align => Set Reconstruction region => Reconstruct => Smooth => Simplify => Unwrap => Texture => Export.

Just change 2Ds view (Thumbnail ) to 1Ds view and select proper COMPONENT where images are aligned

Please go to WORKFLOW->SETTINGS->START BUTTON and configure it for you particular workflows.
For Texturing of the model we highly recomend to do it bystep by step UNWRAP and then TEXTURE,
or if you experienced setup DEFAULT texturing options ( RECONSTRUCTION->SETTINGS->COLORING/TEXTURING->DEFAULT UNWRAP PARAMETERS )
- Actually I had to go back to a “simplify” step which leads me to this 3rd issue: why “simplify” is excluded from the “start” button? Even in case it would work, at the end I would get ~100mln poly mesh which is not usable in my case. I would have to destroy 50% of work, go back and simplify, unwrap and texture it.

The START button is not all around case solution, its used for particular workflows where it can be fully utilised, but cant be used on everything.
4)With this one I’m not sure, because once I got a good results and in other project not really.

Yes TEXTURE button calculate even UNWRAP ( UVs ) as its prerequirement for actual Textures but again it depend on workflow
if its not better to have done it in step by step fasion. Its prerequirement if you do larger, more complex work to do it in steps and check if the setting you are using good for particualr projects.
Thanks for the quick answers!
Well, isn’t the fact that you recommend step-by-step option a proof that a “Start” button doesn’t do what it supposed to?
I imagine it like this: I set all steps in the settings, hit the start button and go home. PC is working over night and at the morning I have to only save and close the project. So it would be great to even add an “export” option to the “start” button.
Sitting and waiting for each step, just to hit “next”, is a bit…weak. Plus I have to block my CPU/GPU during the day when I have do other stuff.
What do you think?
Not all projects will work that way.
Depending on how many photos you have not all of them may align easily. You’ll have to make use of control points eventually.
Also, you may get more than one component where you may have to run alignment again with “Merge Components Only” set to “True”. to combine multiple components.
Photogrammetry is not a one-button-makes-it-all solution. It tends to be a very interactive and iterative process.
The One-Button-Solution only works well when you work within a defined environment with defined cameras. Like, a stationary Photo booth for capturing humans, animals, etc.
start button, really should be a batch builder instead, that you can adjust.
its a bit pointless now, need to be able to add at least a simplify before it would become useful.
I’d much rather see it replaced with something that is flexible and you can switch things around.
then submit it to network for processing
Unfortunately, batch processing s reserved for the grown up version… :shock:
