[Max] I need help! / Seamless texture problem when bitmap tiling is other than 1

« on: 2025-03-21, 06:36:02 »

I have several seamless fabric bitmaps that I use to create materials. The maps are of different sizes. That's why I correctly size them using bitmap tiling. Unfortunately, when I use a tiling value of something other than 1, the texture is not seamless anymore. What can I do? I also tried real-world map scale, but the issue remains for values other than default.
(On a side note, why is the default real-world scale size 0.1cm? How can I change it?)

...or place a temporary Corona Light over the table top so that you can see its reflection. Once you are happy with your material setup, remove that temporary light.

I tried and it works. Thank you.

This is because in your scene there is nothing to reflect other than just plain color and empty space. You can override the reflection with some HDRI either on full scene or on some specific material. see screenshot attached.

Wow! It worked. Very easy and quick solution. Thanks.

Did you try to change the lighting to a more contrasty one? Your material previews in the material editor looks very glossy, so it's most likely that the "issue" is in the lighting. If it's very diffuse, which is quite common in studio setup, then materials might struggle to show clear glossy reflections, because there's not enough contrast for that.

How can I achieve a more contrasty lighting? I am new to studio setup rendering. I am using a key light, a fill light and white environment light.

[Max] I need help! / [solved] Material Glossiness Problem

« on: 2025-03-15, 16:15:40 »

I rendered a coffee table in a studio lighting setup. The material looks very matte. I tried increasing the reflection level and glossiness of several materials and applied, but the material still looks matte. I am confused about what the issue is. Is it material, lighting, or camera angle? I added the reflection render too. Can anyone help?

which version of corona and 3ds max you used in this scene? did you change versions or color management settings in your 3ds max?

I use 3ds max 2025 and Corona 12. I think the problem started after I updated to these versions.

[Max] I need help! / Incorrect lighting after reopening scene

« on: 2024-11-27, 18:24:21 »

I set up the lighting, rendered a scene, and closed it. I reopened the scene to make some changes, but this time, the lighting was different, even though I saved all the lighting parameters of the previous render. This has happened before.
Something I noticed is that when I save the incorrect lighting render, it saves right. But you can see in the screenshot that the lighting is different in the viewport.
What can I do?

Could be many things, like wrong opacity settings, mapping issues, or anything else. Did you try to render a close-up view and see how the leaves looks when they occupy significant portion of the rendered image?

Thanks. I added another close render of the tree.

I have downloaded a Maxtree tree model. But when I render it in my scene, seems like there are fewer leaves than shown in the thumbnail. I can't understand if this is a material issue or a camera angle issue. Can someone help? I am attaching the thumbnail and my render.

Hi,

Simply try to match the handles to their correct axis lines and if your reference object is going out of the frame then consider zooming out the camera or moving the object so it is in front of the camera. It is normal for the objects on the viewport to move when you change the axis handles. It takes a bit of trial-error and practise to perfectly nail the camera match to your Images.

Thank you for your reply. All the lines cannot be aligned with the reference photo at the same time. If two axis matches, moving the 3rd one mess it up.

[Max] I need help! / Re: Tips on improving render quality

« on: 2023-09-13, 10:42:13 »

Hi,

The obvious first thing to improve, is the texture repetition of the facade. You can use CoronaUVWRandomizer (CoronaMappingRandomizer) map to achieve this randomization. The full how-to article is here.

Beside that, keep in mind that eve if the materials are perfectly set up, the lighting is great, the render can still come out not so good, as a very important aspect of the perceived render quality is the composition of the frame. Think about it as if it is a real project (and a real photo). How would the front yard of the house look like? Does there need to be a walkway or not? And other aspects as well. The best thing here is to observe and check many many references (both real photos and renders of others) and keep improving.

From the quick things you can do is to place a direct light (Sun) comping from top right - this will give a contrast to the facade and the whole architecture of the house and make it more dynamic and interesting. Then you can work on the materials and texture. Then you can add some trees/shrubs in the foreground and make the composition more interesting.

Hope this helps.

Thank you for your suggestions. I will keep these in mind for my next project.

[Max] I need help! / Can't do perspective match

« on: 2023-09-13, 10:40:29 »

I have been trying to do perspective match in 3ds max. But I can't control the vanishing lines properly as shown in YouTube tutorials. It feels like every vanishing line is being affected if I move the handle of a vanishing line. I sometimes lose my reference object too. Can someone suggest me a good tutorial for perspective match or tell me what I am doing wrong? I will appreciate the help. Thank you! I have attached a GIF of how the vanishing line reacts.

Hello good people! I am trying to render an exterior scene inspired by a reference. But I can't get the photorealistic, high-end look of the reference. Can someone suggest to me how I can improve my render quality?Material/resolution/lighting/detailing/etc.; what am I missing? I really appreciate any help you can provide. (It's kind of obvious, but still clarifying the black house is the reference and the brown one is my render.)

If the rest of the map is flat this could be just wrong gamma - make sure your displacement/bump is loaded with 1.0 gamma, not automatic (or 2.2).

Looks like the material was the problem. It was fixed when I turned off the bump map. Thank you for your suggestion.

Do you use displacement on the model or its material? Does the model have turbosmooth modifier which may have different settings for viewport and for render? More info please.

The model was an editable poly with no modifier. Looks like the material was the problem. It was fixed when I turned off the bump map. Thank you for your suggestion.
