Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Shadows too hard, low quality

Hi all

I m working on a new scene, but I ve a problem with the shadows.

I need to smooth them, but I don't found the good settings. I changed Shadow Sharpen, Shadow Bias and Min Roughness ( on Light Source ), but it doesn't work :/

You can see my result here :

How to smooth my shadows ?

Thanks,

Alec

Hi Alec,

I see that you're using a Stationary Directional light. These are both dynamic and static lighting combined. However, you're not seeing any changes by the dynamic portion of the light with the Shadow Bias and Filter Sharpen because the dynamic portion is off by default. You can change this by scrolling down to the tab Cascaded Shadow Maps. Adjust the Dynamic Shadow Distance Stationary to a value you're happy with,.

For the shadows that are baked and already present in your scene to get better more correct looking shadows you'll need to increase the lightmap resolution for the floor mesh where the light and shadow are cast.

Thank you!

This is due to indirect lighting bouncing from the floor onto the back of your door, causing it to look brighter. Since your floor has a very bright texture, a lot of the sunlight that is coming into your room is bounced around rather than being absorbed into the material. You can reduce the effects of indirect lighting by making the textures on which the light falls darker, or changing the settings for indirect lighting itself (you can do this for the light entity and also under 'World Settings').

Personally I prefer to do my textures properly first before I start tweaking indirect lighting settings. I suggest you make a simple scene and experiment with different textures varying in brightness/contrast as well as play around with the settings for indirect lighting so that you can observe its effects on the scene.
