Unity5.x dynamic loading of lightmaps (baking textures), unity5.xlightmaps

The scenario in the project takes 24 hours a day. The Time of day plug-in will not be used here.

Google to an article http://wiki.unity3d.com/index.php/lightmapswitcherto test and find it available. Prepare to put the Code directly into the project and find that there is a problem that is not a problem

The second NaturalSortComparer. cs has not changed.

The usage order is reversed.

1. Switchs has dir and light, and only one of them is canceled.

2. AllLFs indicates that you have several textures. I only use two sets of daytime and night images, and you can have multiple sets of textures. The parameters must be changed below.

3. The length of AllNFs is the same as that of upd.if Switchs are hooked, the length of AllLFS is twice that of AllLFS. Switchs is not hooked and the length is the same as that of AllLFS.

4. the URL in upps indicates the lightmaps path.

Pattern is the suffix

Distance is a remote view

Code with comments

 

Test is available. Because I only use two sets of textures here, I click the event to write the day and night. If there are more than 10 sets of textures, you can control the code. I will not write it here.

This Code also applies to object texture replacement in static scenarios. Texture replacement in dynamic scenes is not considered now. However, I have seen a blog about Dynamic Replacement in Yusong MOMO. You can search for it.

 

I 'd like to hear from you if you have any questions or improvements in your code.
