Average render time for a large scene

1

Hi everyone! I’m fairly new to Shapespark and I have a question about average render times. I’m currently rendering a scene for a virtual tour of a laboratory space that covers an entire floor of a building. I’ll share the parameters below so you can better understand my setup and hopefully help me optimize it.

The scene dimensions are approximately 54,200 mm x 38,900 mm. It includes around 7 rooms: 3 large open spaces with columns and 4 smaller rooms, also with columns. Because of this, I had to create a large number of bounding boxes. As I understand it, bounding boxes cannot touch each other or intersect with walls, floors, or ceilings, so the presence of columns significantly increased the number of bounding boxes in the scene.

The scene also contains many light sources, as it is a laboratory environment, plus sunlight since the building has curtain walls and requires daylight for realism. I need the highest possible quality because this is a virtual tour for clients, so I’m rendering at maximum quality with 6 lightmaps. I’ve read that this is a reasonable number for a large space like mine, but I’m not completely sure.

Finally, and probably the most important factor: I’m rendering on an OMEN 15 laptop from 2017, which I’ve been using as both a gaming and graphic design computer. The C: drive has 19.2 GB of free space, and the system is currently using 14.9 GB out of 15.8 GB of RAM. The render has been running for 21 days, and I would really like to know whether this is a normal render time for a laptop with these specifications.

Thanks in advance for any advice!

Hi, thanks for the detailed description.

In general, a 21-day render time is not typical, even for a large, high-quality scene. Using maximum quality and multiple lightmaps in a complex environment can definitely increase bake time, but this usually means there are a few areas in the scene setup that could be optimized.

To give you more feedback, it would really help to look at the scene directly. Could you please share a link to the scene? I’ll take a look and let you know what could be optimized.

Thanks!

Hi Magda, first of all, thank you so much for your answer. At the end, we just change the PC which was doing the render for a new one, a tower (the old one was a 10 y/o laptop) and it finally takes like 1 hour, so i think the problem was in the hardware i was using , thank you! :slight_smile:
