Title: save incremental
Post by: fco3d on 2014-04-22, 20:54:37
Hello,
I am trying the save incremental on Corona V6 and I found two issues, The first one is the size of saved image seems to be double the original size?  I tried to check my output size and everything but I can not find answer to this.
Also the image save without the render stamp.
Are this issues know, I am missing something in my setup?

Your help is appreciated.

Fco.

Well there is not better answer that the one you find yourself, seems to be the Motto in this forum.
If anybody has the same question, Yes incremental save by default will save double the size of your output image, and the size will depend of the internal calculation resolution, this can be found in the Image filter area.  Not sure why works that way.

Still wonder why the incremental save do not carry the render stamp with info.

If you talking about autosave feature, then file size is bigger because there is additional data in it for resuming rendering, i guess. But it's not meant for saving your final render, use standart render output dialog for that.

it is saved multiplied by the internal resolution so there is absolutely no quality loss after reducing, which would otherwise happen on light edges.

Thanks for the input.
I was wondering about that raw extra data  because comparing the file size of the incremental with the final it is always double, so if there is extra data then it make seance.
I am just using the incremental as a learning method for now, trying to figure out renderings time and comparing mostly with V-Ray, so see who clean first.
I am still new to this progressive method to I am trying o find a way to predict in some way how long I need to coock the images to be acceptable.  At the beginning I though it was based in passes, like I need 100 passes for an 3000 pix image to be clean,  but now I am not sure, let say I have to have 3 images done in one machine, how to know how much to cook.   V_Ray give an estimation that is a good reference, with progressive, hard to know.

Thank again.

passes, when multiplied by the sampling multipliers, represent the amount of brute force work thrown at your image. Some scenes are simpler, and require less work than others. In corona you can currently set only the target amount of work, not target image quality.
