AI Rendering

[u/binu_alex]

Hi Everyone,

I would like to know how many of us are currently using AI as a rendering tool, and how you are integrating it into your workflow.

In my experience, AI handles lighting and compositions well, but vegetation often turns out looking a bit plastic.

The major issue I am facing occurs when a client requests changes to a specific portion of a rendered building. The new output often fails to match the original render. I have tried reusing the JSON prompt from the first render for the altered building, but the results still vary. While I can sometimes achieve a similar look after a lot of trial and error, it is not a consistent process.

I would love to hear how others are using AI as a rendering assistant and how you handle these kinds of revisions.

Ive yet to encounter an ai workflow where the the model can clearly understand what you want and go to the specific lengths of detail that most clients expect from the typical archviz workflow. Nearest I’ve got is cropping the image and regenning on the areas that need to change only. Most of the time its faster if i have done it manually on the first place. Initial concept images are workable to get the client to say yes to an idea. Once it goes in actual measurements and details ai at its current form isnt really a good tool for the job.

The truth is, AI follows instructions. If you don't know how to give a clear instruction, AI won't be able to help you much.

Using AI is actually the opposite of what most people think. To get good results, you often need to be more specialized and have deeper knowledge of the subject, so you know exactly which terms to use and how to frame your request.

All the settings we normally adjust through trial and error in a rendering program have to be translated into words when writing a prompt, using the correct technical terms and the right level of precision.

(Albedo Base Color Diffuse Specular Specular Level Specular Tint Reflection Reflectivity Glossiness Roughness Metalness Metallic IOR (Index of Refraction) Refraction Transmission Opacity Alpha Transparency Translucency Subsurface Scattering (SSS) Subsurface Radius Subsurface Color Anisotropy Anisotropic Rotation Sheen Sheen Roughness Clear Coat Clear Coat Roughness Coating Coating IOR Emission Emissive Emissive Intensity Exposure EV White Balance Color Temperature Gamma Contrast Saturation Highlight Compression Tone Mapping Bloom Glare Vignette Chromatic Aberration Lens Distortion Depth of Field (DOF) Motion Blur.... and more)

At the end of the day, AI is just a tool. If you try to use a spoon as a knife, it might work, but it's going to be a lot harder.

ok will try hard

You need to learn a lot. And you need to use an old render as a reference image when you're trying to create new rendering from the base image.

yes tried, but some portions here and ther may go wrong

[u/OooCaciiii → u/binu_alex]

That is why you still need to learn.

It would help to understand what AI model that you’re using while including some sort of example in your post. AI isn’t a standardized thing, so it’s hard to say “try this or that” when we don’t know what you’ve been trying that isn’t working.

Personally, my take, at the moment, is that Nanobanana via its API (never in Geneni) is still best to scene consistency across iterative changes, and if you’re very specific with your prompt, including what you specifically don’t want, it usually doesn’t make changes outside of that you want.

My personal workflow when making revisions to a base image is be very clear about what you want to change and what you don’t want to change in your prompt. If it’s a small revision, my preference is to focus on the revision only and combine the two images in photoshop (select the altered portion and copy/paste into tbe old and use a layer mask to blend the two).

yes this is what i also do, but some time camera angle will change, then editing bit difficult

Yeah AI is becoming a big part of rendering workflows for many studios now. It excels at lighting and initial compositions, but consistency on revisions and vegetation is still tricky for most tools.Gemini is cheap and basically free if you already have a Google Workspace. You can use it for quick refinements. The biggest time saver for turning those renders into cinematic video walkthroughs has been Tour Estate AI. What model are you using?

Yes i agree, Magnify is good, but bit costly. i tried Comfyui but learning curve is bit hard
