Animgraph-Blend node-Alpha Scale Bias-larger values imprecise

anonymous_user_2a254ae9 · January 9, 2015, 11:43am

In animation graph, the blend node (simple one, but maybe it’s a case of other nodes with alpha scale bias too), if you go edit the Alpha Scale Bias values, once you set values where the difference between them is larger then 10, both values start to be “imprecise”, e.g. setting min = 5 and max = 20 result in values like min=4.999970 and max=19.999895.

Edit: this is happening with 4.6.1

Hi ,

Looking at the documentation for the blend node, you are only supposed to blend between 0.0 and 0.1 as shown here:

Let me know if this does not address your question.

Thanks

Hello, while it’s true that alpha is supposed to be between 0.0 and 1.0, I was talking about “Alpha Scale Bias” values which can be found in the details tab when the blend node is selected.

Hi ,

Thanks for the clarification. I was able to reproduce the issue and using the information you’ve provided, I have entered the following bug report, JIRA [UE-7944]. Should this issue be addressed in a future build of the engine, an update will be added to this post.

Thanks again for the feedback.
