expression must not be a pointer error with RadialAccelModifier

[jiftoo]

Hello!

I've been playing around with complex particle systems and noticed that I can't use any custom attributes with RadialAccelModifier.

Here's an example:

RadialAccelModifier::new(
	writer.lit(Vec3::ZERO).expr(),
	(writer.lit(-1000.0) * writer.attr(Attribute::AGE)).expr(),
)

// add it to EffectAsset later

And here's the shader error I get:

2024-02-14T18:38:38.292587Z ERROR bevy_render::render_resource::pipeline_cache: failed to process shader:

    │
    = the value accessed by a `.member` expression must not be a pointer

Is this a limitation of some sort? I quickly tested non-radial AccelModifier and didn't seem to get any errors.

Thank you!

It's a bug, thanks for flagging, should be easy to fix a priori.
