KTX_RenderSlot.py issue

[EugeneDudavkin]

Hello, if you add more slots (>8) then script give an error

 line 111, in ui
    test_active = bool(scn.ktx_occupied_render_slots.data[i] == '1')
IndexError: string index out of range

you've got to provide more information.. I need to be able to get that same error.. state all your steps, otherwise I can't do anything about it. Just starting fresh and generating a bunch of render layers just works (even on 3.4.0 alpha)

[EugeneDudavkin]

1. After the Blender starts, Toggle System Console (Window - Toggle System Console).
2. Go to Rendering workspace, open "Image" tab.
3. Add Render Slot (by pressing "+" icon, 2-3 slots).
4. Then select first slot and press F12 (Render Image).
5. See the error in the console.

thank you.. I can reproduce the error.. will investigate/fix! btw. there is no need to manually add render slots. in the preferences of the addon you can select "advanced mode" and then "Auto Advance" in the render scene properties.

I found the cause.

class OccupiedSlots:
    data = '00000000'

if data length = render slots length, then error disappears. So if we add 2 more zeros to data, and then after blender starts we add 2 more slots, the error will not happen.

yes.. when you "manually" add slots, the addon doesn't get notified about it.. it only gets notified after a render to recalc the amount of slots. I'm looking for a handler to notify my addon when a slot is manually added

[EugeneDudavkin]

Why I do not use "Auto Advance", its because I need to see render image after the end of rendering and for other thing. That's why I made an "additional" addon for your addon (based on your code for checking render slot empty or not). It checking if render slot is empty - then render, if render slot not empty - then render in the next slot, if slot not empty and it's the last slot - then add new slot and render. And option to rewrite next slot (empty or not).

Updated the addon to catch the error, BUT there's not much else I can do... There is no way for my addon to get notified by blender whenever a user adds a renderslot. (with my knowledge) Only thing I can do is add a "refresh" button to recalc all slots. I'll do that at a later time, have to get back to my current project ;-) Cheers!

[kostex]

added the refresh button ;-)
