LOOK FOR BOX TYPE IMAGES
I need to annotate each SINGLE plant separately from others, for accurate annotation, right now I've it scripted for ID MASK. It gives each object from a specifically named collection iterated ID pass, renders original scene in .png, and then renders and converts pixels (every pixel, which is not black) from every ID MASK image to .json. But as you can see it doesn't works as expected. Is there something similar I could do with cryptomatte? Again, For annotation I need to know in advance which objects which color will use or something like that to know exactly or define an object. maybe I can adjust emission shader or make my own so it can handle transparent textures correctly as well? or something along those lines UPD cryptomatte works only when I render plants separately from scene Look here cryptomatte whole scene vs cryptomatte plants only
Blender doesn't render all pixels on distant objects, it gets better when I make resolution higher, like 4k, but it doesnt fixes my problem, but makes image pixels better. Also raising sample doesnt help. I tried to render with denoising and AA in compositor, that didnt help. How can I fix this, so it will render all object pixels on ID MASK using box pixel type? I need an alpha of an object as an ID MASK, for accurate object annotation.
Render Resolution: 1280x720
Pixel type: Blackman-Harris
Pixel width: 0.01
Box type pixels looks so much better on the Image, but ID Mask dont recognize them, now how to fix this one?
Here's an addon, which do almost what I needed, but it uses emission shader, which doesnt work with custom textures.
By annotation I mean assigning each pixel of the original (rendered) image a corresponding value of instanceId
Where instanceId maps a specific blender object.
For now I just need objectId and categories.
Right now I'm using ID masks which is the only reliable solution I've come up with.
As you can see I've tried a lot of other options such as: Cryptomatte Emission shader Denoising Playing with AlphaTreshold
Since ID masks don't work as reliable as I thought they would. I was thinking about writing my own shader that will use emission (to get the perfect color) and some magic to fix the transparent textures.
I know I should start a new question, but... how to achive a solid color with nodes? If there's a way to get a fully opaque color w/o aa or any kind of transparency? That would solve my problem perfectly. Here's my node attempt:
Cryptomatte did the job, but it needs a manual nodes pre-setup
