Welcome to the forum @glance -

It would be helpful to know more information about your model run and results. Does the _quality\_c.tif_ output also have values that are all 0? Does the map for _deg\_sum\_c\_1980,tif_ show any visible difference in values, even though the legend says that it’s all 0?

And please upload the log file that is created in your Workspace. The filename is long and ends in “.txt”, and has additional information that might help us troubleshoot. Thank you.

Hello, swolny. I meet the same question. And the map for quality\_c.tif looks right. I will upload the log file for your help. Thank you so much.

你好，你如果使用的是最新版本的话，可以把威胁距离改一下，因为最新版本好像默认距离单位和之前的不一样，我改了之后就正常了
