Just to clarify for other users who may read that. You do not loose actual credits if you cancel a render or if an error happens during render time. Credits are deducted from your account only at the end when the render is a success.

@rdmdkbrx you are talking about free renders not credits.

Well I had the credits box checked as I was rendering a larger size with HD minifigures, but if as you say credits are not deducted until the render successfully completes, then that's great. Though I'm certain I have seen a credit deduction from a canceled render a few times before.

@rdmdkbrx If the project is cancelled while a frame from this project is rendering then this frame will be fully rendered and price deducted from the user credits. It is not possible to cancel a frame which is rendering. The code related to credit calculation has been thoroughly tested and verified 😉

Do not hesitate to get in touch when you think something went wrong with credits. It will be easily resolved. Thanks.
